Here’s my preview of some of the best celestial events for 2023. Mine is certainly not an exhaustive list. I’ve picked just one event per month, and I’ve focused on events best for unaided eyes or binoculars, and visible from North America. (So the solar eclipse of April 20 visible from Australia and the South Pacific, and the two minor lunar eclipses this year don’t make the cut!)

As 2023 opens, Venus is beginning its climb into the evening sky, while Saturn is sinking into the sunset. The two planets pass each other on Sunday, January 22, when they appear just one-third of a degree apart in the twilight. Use binoculars to pick out dimmer Saturn. And look for the thin day-old crescent Moon just over a binocular field below the planet pair.
A month later, on Wednesday, February 22, Venus has now ascended higher, preparing to meet up with descending Jupiter. But before they meet, the crescent Moon, with its dark side lit by faint Earthshine, joins the planets in a particularly close conjunction with Jupiter. They will appear about 1° (two Moon diameters) apart, with Venus about a binocular field below.
Here’s a date to circle on your calendar. On Wednesday, March 1 the sky’s two brightest planets, Venus and Jupiter, pass within half a degree of each other, in arguably the year’s best conjunction. They’ll be close enough to frame nicely at medium power in a telescope, though the featureless gibbous disk of Venus will appear small, about the third the size of Jupiter’s banded globe. But Venus is by far the brighter of the two worlds.
If you want to check Mercury off your sighting list this year, this is a good week to do it. On April 11 Mercury reaches its greatest angle away from the Sun in the evening sky, and for northern hemisphere viewers, is angled at its highest in the western sky. Even so, look just a binocular field above the horizon. While you’re at it, look higher for the fine sight of Venus near the Pleiades star cluster.
Wednesday, May 17 brings a chance to see the crescent Moon pass in front of Jupiter. But it will be a tricky event to catch. While most of North America and parts of Northern Europe can see the occultation, it occurs in the daytime sky with the Moon only 25° west of the Sun. However, locations along the West Coast of North America can see either the start or end of the occultation in a bright pre-dawn sky. Vancouver, Canada sees Jupiter disappear before sunrise, while Los Angeles – the view shown above – sees Jupiter reappear just before sunrise. Other locations will see a close conjunction of the Moon and Jupiter low in the dawn sky.
As June opens we have Venus still shining brightly in the evening below much dimmer Mars, now far from the Earth and tiny in a telescope. But it’ll be worth a look this night even in binoculars as the red planet passes in front of the Beehive star cluster, also known as Messier 44. If you miss June 2, Mars will be close to the Beehive the night before and after.
Venus has been bright all spring, but on July 7 it officially peaks at its maximum brilliance, reaching a blazing magnitude of -4.7. It reached its greatest angle from the Sun a month earlier on June 4 and is now dropping closer to the Sun each evening. But you still can’t miss it. What you might miss is dim Mars above, now close to the star Regulus in Leo. Mars passes 3/4 of a degree above Regulus on July 9 and 10. You’ll need binoculars to pick out the pairing.
Everyone looks forward to the annual summer stargazing highlight – watching the Perseid meteor shower. This is a good year, with the peak hour of the shower falling in the middle of the night of August 12/13 for North America. That’s a Saturday night! But most importantly, the waning Moon doesn’t rise until the wee hours, as shown here, so its light won’t wash out the meteors. Plan to be at a dark site for an all-night meteor watch.
By September Venus has made the transition into the morning sky and shines at its greatest dawn-sky brilliance on September 19. It will then be joined by Mercury, with the inner planet reaching its greatest angle away from the Sun on September 22 shown here. This is the best morning appearance of Mercury for Northern Hemisphere observers. The view this morning bookends the view five months earlier on April 11. If you are away from urban light pollution, also look for the faint glow of Zodiacal Light in the pre-dawn sky before Mercury rises.
October is solar eclipse month! On Saturday, October 14 the shadow of the Moon passes across all of North America and most of South America. Everyone on those two continents sees a partial eclipse of the Sun. But those along a narrow path sweeping across the western U.S. and down into Mexico, Central America and across northern South America can see a rare “ring of fire” eclipse as the Moon’s dark disk eclipses the Sun, but isn’t quite large enough to totally cover it. This is an “annular” eclipse. The view above is from Albuquerque, New Mexico, one of the largest U.S. cities in the path of annularity, second only to San Antonio, Texas.
This is the path of annularity across the western U.S. To see the Moon pass centrally across the Sun (the “ring of fire”) you have to be somewhere in that grey path. Outside the path you will see only a partial eclipse of the Sun. For detailed and zoomable eclipse path maps like the one above, please visit EclipseWise.com.
Close conjunctions between the crescent Moon and Venus are always notable. Get up early on Thursday, November 9 to see the 26-day-old Moon shining only a degree below Venus. Venus reached its greatest angle away from the Sun on October 23. It is now descending back toward the Sun, but remains high in the morning sky in early November.
Though it usually puts on a better show than the summer Perseids, the Geminid meteor shower is not as popular because it’s cold! But this is also a good year for the Geminids as it peaks only two days after New Moon. The best night might be Thursday, December 14, but a good number of meteors should be zipping across the sky the night before on December 13, shown here. Start watching at nightfall and go as long as you can in the chill of a December night.

Good luck in your stargazing and clear skies for 2023!
However, the reward was the sight of the reddened Moon from one of my favourite locations in Alberta, Reesor Lake, in Cypress Hills Interprovincial Park.
The eclipse in question was the total lunar eclipse of May 15/16, 2022. As with any eclipse, planning starts with a look at the weather forecasts, or more specifically cloud forecasts.
A few days prior, conditions didn’t look good from my home, to the west of the red marker.
But as the chart from the app Astrospheric shows, very clear skies were forecast for southeast Alberta, in the Cypress Hills area, where I have shot many times before.
Except as eclipse evening drew closer, the forecast got worse. Now, the clouds were going to extend to my chosen site, with a particularly annoying tongue of cloud right over my spot. Clouds were going to move in just as the total eclipse began. Of course!
I decided to go for it anyway, as the Moon would be to the east, in the direction of the clear skies. It didn’t need to be clear overhead. Nor did I want to drive any farther than I really needed, especially to another location with an unknown foreground.
The spot I chose was one I knew well, on the west shore of scenic Reesor Lake, near the Alberta/Saskatchewan border, but on the Alberta side of Cypress Hills Interprovincial Park.
Handily, TPE provides moonrise times and angles for the chosen location, as well as eclipse times for that time zone.
The companion app, TPE 3D, provides a preview of the scene in 3D relief, with the hills depicted, as a check on Moon altitude and azimuth with respect to the horizon below.
As you can see the simulation matched reality quite well, though the image below was from an earlier time than the simulation, which was for well after mid-totality.
However, true to the predictions, clouds were moving in from the west all during the eclipse, to eventually obscure the Moon just as it entered totality and became very dim. Between the clouds and the dark, red Moon, I lost sight of it at totality. As expected!
Below is my last sighting, just before totality began.
However, I was content at having captured the eclipse from a photogenic site. More images of a complete eclipse would have been nice, but alas! I still consider the chase a success.
Just for fun, I shot a quick panorama of three segments, and it turned out to be my favourite image from the eclipse, capturing the scene very well. Pelicans and geese were plying the calm waters of the lake. And owls were hooting in the woods. It was a fabulous evening!
Before departing, I took my customary “trophy” shot, of the eclipse hunter having bagged his game.
Interestingly, this eclipse was a close repeat of one 19 years earlier to the day, because of the so-called Metonic Cycle where eclipses of the Sun and Moon repeat at 19-year intervals on the same calendar day, at least for 2 or 3 cycles.
On May 15, 2003, we also had a total lunar eclipse in the early evening, with the eclipsed Moon rising into a spring twilight sky. I also chased clear skies for that one, but in the opposite direction from home, to the southwest, to the foothills. At that time it was all film, and medium format at that.
So it was another (partially!) successful eclipse chase.
The next opportunity is on the night of November 7/8, 2022, a time of year not known for clear skies!
Just once I would like to see one from home, to make it easier to shoot with various telescopes and trackers, as the reddened Moon will be west of the photogenic winter Milky Way, and very close to the planet Uranus. Plus for me in Alberta the November eclipse occurs in the middle of the night, making a home eclipse much more convenient. After that, the next chance is March 13/14, 2025.
But no matter the eclipse, I suspect another chase will be in order! It just wouldn’t be a lunar eclipse without one.
Two total eclipses of the Moon, an all-planet array across the sky, and a fine close approach of Mars highlight the astronomical year of 2022.
In this blog, I provide my selection of the best sky sights of 2022. I focus on events you can actually see, and from North America. I also emphasize photogenic events, such as gatherings of the Moon and planets at dawn or dusk, and the low Full Moons of summer.
The sky charts are for my longitude in Alberta and my home latitude of 51° N, farther north than many readers will likely live. From more southerly latitudes in North America, the low planet gatherings at dawn or dusk will be more obvious, with the objects higher and in a darker sky than my charts depict.
Feel free to share the link to my blog, or to print it out for reference through the year.
Highlights: Lunar Eclipses, Planet Array and Mars
As in 2021, this year we have two lunar eclipses, both total this year, six months apart in May and in November. On the night of May 15/16 eastern North America gets the best view of a deep total eclipse that lasts 85 minutes. Six lunar cycles later, western North America gets the best view of another 85-minute-long total lunar eclipse.
The year begins with four planets in the evening sky, but not for long. They all soon move into the morning sky for the rest of the first half of 2022. In fact, in late June we have the rare chance to see all five naked eye planets lined up in order (!) across the morning sky.
The “star” planet of 2022 is Mars, as it reaches one of its biennial close approaches to Earth, and a decent one at that, with its disk relatively large and the planet high in the winter sky, making for excellent telescope views. The night Mars is directly opposite the Earth and at its brightest coincides with a Full Moon, which just happens to also pass in front of Mars that night! That’s a remarkable and rare event to round out a year of stargazing.
The RASC has also partnered with Firefly Books to publish a more popular-level guide to the coming year’s sky for North America, as the 2022 Night Sky Almanac, authored by Canadian science writer Nicole Mortillaro. It provides excellent monthly star charts to help you learn the sky.
The year begins with a chance to see four planets together at dusk. But catch them quick!
January 4 — Mercury, Venus (just!), Jupiter and Saturn, plus the Moon
Venus is sinking out of sight fast, as it approaches its January 8 conjunction with the Sun, putting it out of sight. But Mercury is climbing higher, approaching its January 7 greatest angle away from the Sun.
This night the waxing crescent Moon appears below Saturn. It was below Mercury on January 3, and will be below Jupiter on January 5. On January 13, Mercury shines 3.5 degrees (°) below Saturn, just before both disappear close to the Sun.
January 17 — The 2022 Mini-Moon
The Full Moon this night is the most distant, and therefore the smallest, of 2022. Shoot it and the Full Moon of July with identical gear to collect a contrasting pair of Mini and Super Moons, as above.
January 29 — Waning Moon and Morning Planets
By the end of January, Mercury and Venus have both moved into the morning sky, where they join Mars. The waning crescent Moon appears below magnitude 1.5 Mars this morning, as the famed red planet begins its fine appearance for 2022.
The main planet action migrates to the morning sky, while Zodiacal Light season begins in the evening.
February 16 — Mercury As a Morning Star
Though not a favourable elongation for northern latitudes, on February 16 Mercury reaches its highest angle away from the Sun low in the eastern dawn, below Venus and Mars, with Venus having just reached its greatest brilliancy (at a blazing magnitude -4.9!) on February 12, shining above much dimmer Mars. (Magnitude 0 to 1 is a bright star; magnitude 6 is the faintest naked-eye star; any magnitude of -1 to -5 is very bright.)
While at magnitude 0, elusive Mercury shines a magnitude and a half brighter than Mars, Mercury’s lower altitude will make it tougher to see. Use binoculars to pick it out. But Venus remains a brilliant and easy “morning star” for the next few months.
February 18 — Zodiacal Light Season Begins in the Evening
From sites away from light pollution look for a faint glow of light rising out of the southwest sky on any clear evening for the next two weeks with no Moon. This glow is caused by sunlight reflecting off cometary dust particles in the inner solar system. The next moonless window for the evening Zodiacal Light is March 20 to early April. Spring is the best season for seeing and shooting the Light in the evening sky.
February 27 — Moon Joins the Morning Planet Party
The waning crescent Moon appears very low below Mars and Venus, with Mercury still in view, and Saturn just beginning to emerge from behind the Sun.
Equinox brings a favourable season for great auroras, while the morning planets begin to cluster in the east.
March 1 on — Prime Aurora Season Begins
While great auroras can occur in any month, statistically the best displays often occur around the two equinoxes in spring and autumn. No one can predict more than 12 to 48 hours ahead (and still with a great deal of uncertainty) when a display will be visible from mid-latitudes. But watch sites such as SpaceWeather.com for heads-up notices.
March 1 on — Flaring Geosat Season Begins
In the weeks prior to the spring equinox, and in the few weeks after the autumn equinox, the string of communication satellites in geostationary orbit catch the sunlight and flare to naked-eye brilliance. Long-exposure tracked photos of the area below Leo (in spring, as here) will catch them as streaks, as the camera follows the stars causing the stationary satellites to trail.
March 12 — Venus and Mars in Conjunction
Venus and Mars reach their closest separation 4° apart low in the southeastern dawn sky.
March 20 — Equinox at 11:33 a.m. EDT
Spring officially begins for the northern hemisphere, autumn for the southern, as the Sun crosses the celestial equator heading north. Today, the Sun rises due east and sets due west, great for urban photo ops.
March 27 — Moon and a Planetary Triangle
The waning crescent Moon appears to the west of Venus and Mars, with Venus about 2° above Saturn. The view will be better the next morning, March 28, with the thin Moon directly below the close pairing of Venus and Saturn. But the Moon will be even lower in the sky, making it more difficult to sight.
Mercury puts on its best evening show of 2022, near the Pleiades, and with a possible comet nearby. The month ends with a very close conjunction of Venus and Jupiter at dawn.
April 1 — Milky Way Arch Season Opens
With the Moon out of view, the next two weeks bring good nights to shoot panoramas of the bright summer Milky Way as an arch across the sky, with the galactic core in view to the south. Catching the arch takes a very late-night shoot in early April. But the Milky Way moves into prime position two hours earlier each month.
April 5 — Mars and Saturn 1/2° apart
The two planets appear almost the same brightness as a close “double star” in the dawn, not far from brighter Venus. Mars and Saturn will also be close the morning before, on April 4.
April 27 — Moon Joins Venus and Jupiter
Jupiter is now emerging from behind the Sun to meet up with Venus, for a grouping of the sky’s two brightest planets. On this morning the waning Moon appears 4.5° below the pair.
April 29 — Mercury Appears Beside the Pleiades
Just as Mercury reaches its greatest angle away from the Sun for its best evening appearance of 2022, it also appears just 1° away from the famous Pleiades star cluster low in the west.
April 30 — Venus and Jupiter in Close Conjunction
This is an early morning sight well worth getting up for! Venus passes only 1/3° below Jupiter this morning, but low in the eastern dawn sky. They will be almost as close on May 1.
April 30 — A Bonus Comet?
Comet PanSTARRS (C/2021 O3) might become bright enough to be a binocular object, and a photogenic target, right next to the Pleiades and Mercury pairing. Maybe! Some predictions suggest this comet could fizzle and break up earlier in April. Even if the comet survives and performs, you’ll need a very clear sky to the northwest to catch this rare sight.
On May 15-16 a totally eclipsed Moon shines red in the south at midnight for eastern North America, and in the southeast after sunset from the west.
May 15-16 — Total Eclipse of the Moon
The first of two total lunar eclipses in 2022 can be seen in its entirety from eastern North America, with totality beginning at 11:30 p.m. EDT on May 15 and lasting 85 minutes until 12:55 a.m. EDT. At mid-eclipse just after midnight from eastern North America the Moon will appear nearly due south, with the summer Milky Way to the east, shining brightly as the sky darkens during totality. Travel to a dark site to see and shoot the Moon and Milky Way.
Those in western North America see the totally eclipsed Moon rising into the southeast with some portion of the eclipse in progress, as depicted above. Once the sky darkens, the reddened Moon should become visible. Over a suitable landscape this should be a photogenic scene, though with the core of the Milky Way not yet risen. But a Milky Way arch panorama with a red Moon at one end will be possible. Choose your scenic site well!
See Fred Espenak’s EclipseWise.com page for details on timing and viewing regions. The dark region on this map does not see any of this eclipse.
May 18 — Red Planet Meets Blue Planet
Mars passes just 1/2° south of Neptune this morning, though both planets are very low in the east. They will appear close enough to frame in a telescope (the red circle is 1° wide).
May 24 — Moon with Mars and Jupiter
As it does every month in early 2022, the waning crescent Moon joins the morning planets, on this day grouping with Mars and Jupiter before dawn.
May 27 — Moon with Venus, plus Mars and Jupiter Close
Later that week the thinner waning Moon passes 4° below bright Venus, still shining at magnitude -4. But higher up Mars and Jupiter are reaching a close conjunction, passing about 1/2° apart on May 28 and May 29. Mars is still a dim magnitude +0.7; Jupiter is at -2.2.
Noctilucent cloud season begins for northerners, as does prime Milky Way core season for southerners. But the unusual sight is the line of all five naked eye planets, and in order!
June 1 on — Milky Way Core Season at its Prime
In early June with no Moon to interfere, and monthly for the next four months, the Milky Way core is ideally placed to the south through the night for nightscapes. However, for those at more northern latitudes the sky in June doesn’t get dark enough to make deep Milky Way shots feasible.
June 1 on — Noctilucent Cloud Season Begins
Instead, northerners are rewarded by the occasional sight of noctilucent clouds to the north through June and well into July (even into August for sub-arctic latitudes). The Sun illuminates these high-altitude electric-blue clouds during the weeks around the summer solstice. However, there is no predicting on what night a good display will appear.
June 14 — First of the Summer Supermoons
The Moon is full on the night of June 14-15, when it also reaches one of its closest perigees (closest approach to Earth) of 2022. In modern parlance, that makes it a “supermoon.” It will look impressive shining low in the south all night, with the low-altitude “Moon illusion” making it appear even larger. It is a good night for nightscapes with the Moon, though exposures are a challenge — try blending short exposures for the lunar disk with long exposures for the sky and ground.
June 21 — Solstice at 5:14 a.m. EDT
Summer officially begins for the northern hemisphere, winter for the southern, as the Sun reaches its most northerly position above the celestial equator. The Sun rises farthest to the northeast and sets farthest to the northwest, and the length of daylight is at its maximum.
June 24 — All Planets in a Row
As fast-moving Mercury rises into view at dawn in mid-June, it completes the set to provide the rare chance to see all five naked eye planets — Mercury, Venus, Mars, Jupiter and Saturn — in a row along the ecliptic, the path of the planets. Even more fun, they are in the correct order out from the Sun! The scene shown here depicts the morning of June 24, when the Moon sits between Venus and Mars, just where it should be in order of distance from the Sun as well.
A panorama of several stitched images will be best for capturing the scene which spans 120°. Uranus and Neptune are there, too, though not in order and faint enough (below naked eye brightness) they will be tough to capture in a wide-angle scene. Long exposures with a tracker might do the job! But by the time Mercury rises high enough, the sky might be getting too bright to nab the faintest planets.
June 26 — Inner World Gathering
The select club of just inner worlds gathers for a meeting this morning, with the waning crescent Moon 2.5° above Venus. The rising stars of Taurus serve as a fine backdrop in the dawn twilight.
Once the pesky full supermoon gets out of the way, the heart of Milky Way season will be infull swing.
July 13 — Second of the Summer Supermoons
It will be a battle of summer supermoons in 2022! But July’s Moon wins on a technicality, as it is ever so slightly closer (by about 200 km) than the June Moon. It also appears slightly farther south, so lower in the sky than a month before. This is a good night for lunar (looney?) photo ops, though don’t expect to see the Milky Way as shown here — moonlight will wash it out.
July 26 — Dawn Moon and Morning Star
Another photo op comes on July 26 when the waning crescent Moon passes 3° above Venus, still bright at magnitude -3.8. The last week of July and the first week of August are prime weeks for shooting the Milky Way core to the south over scenic nightscapes, assuming we get clear skies free of forest fire smoke.
The popular Perseid meteors are mooned out, but late in the month under dark skies, the Milky Way reigns supreme.
August 1 — Red Planet Meets Green Planet
As it did in May, Mars meets up with an outer planet, passing close enough to Uranus this night for both to appear in a low-power telescope field (the red circle is 2° wide).
August 12-13 — Perseid Meteor Shower Peaks
The annual and popular Perseid meteor shower peaks tonight, but with a nearly Full Moon in Aquarius (as shown above) lighting the sky all night. Under a transparent sky, you’ll still see some bright meteors radiating from Perseus in the northeast. But you’ll need to be patient, as bright meteors are infrequent. But why not enjoy a moonlit summer night under the stars anyway?
August 14-15 — Saturn at Opposition
Saturn is at its closest and brightest for 2022 tonight, rising at sunset and shining due south in eastern Capricornus in the middle of the night. Through a telescope the rings appear tipped at an angle of 13°, about half the maximum possible at Saturnian solstices. The northern face of the rings is tipped toward us.
August 16 on — Prime Milky Way Season
After it spoils the Perseids, the waning gibbous Moon takes a long time to get out of the way. As it does so, mid-August brings some good nights to shoot the Milky Way to the south as the rising waning Moon to the east illuminates the landscape with warm “bronze hour” lighting. By the last week of August, nights are finally moonless enough for an all-night dark-sky shoot.
August 25 — Thin Moon Above Venus
Those enjoying an all-nighter under the stars on August 24 will be rewarded with the sight of the thin waning Moon and Venus rising together at dawn on August 25. They will be 5° apart in the morning twilight, against the backdrop of the winter stars rising.
It’s Harvest Moon time, with this annual special Full Moon coming early before the equinox this year.
September 1 on — Prime Aurora Season Begins
As in spring, some of the best weeks for sighting auroras traditionally occur around the autumn equinox. Solar activity is on the rise in 2022, heading toward an expected solar maximum in late 2024 or 2025. So we can expect some good shows this year, including some that should extend south into the northern half of the lower 48 in the U.S.
September 10 — Full “Harvest” Moon
Occurring 12 days before the equinox, this is the closest Full Moon to the equinox, making it the official Harvest Moon of 2022. With it occurring early this year, the Harvest Moon will rise well south of due east at sunset and set well south of due west at sunrise on September 11.
Autumn officially begins for the northern hemisphere, spring for the southern, as the Sun crosses the celestial equator heading south. As in March, the Sun rises due east and sets due west for photo ops on east-west aligned roads, as above.
September 23 — Zodiacal Light Season Begins in the Morning
With no Moon for the next two weeks, from sites away from light pollution look to the pre-dawn sky for a faint glow of light rising out of the east before twilight brightens the morning sky. The end of October brings another moonless morning window of opportunity for the Zodiacal Light.
September 26-27 — Jupiter at opposition
Jupiter, now in southern Pisces, reaches its closest and brightest for 2022 tonight, also rising at sunset and shining due south in the middle of the night. Jupiter has now moved far enough along the ecliptic to place it high in the sky for northern observers, providing us with sharper telescope views than we’ve had for many years.
Mercury rises into the dawn, while the Moon occults the planet Uranus.
October 8 — Mercury at Its Morning Best
This is the best time to sight Mercury in the morning, as it reaches its greatest angle away from the Sun today, while the steep angle of the ecliptic on autumn mornings swings the inner planet up as high and clear from horizon haze it can get for the year.
October 11 — Moon Hides Uranus
While many observers might not have seen Uranus, here’s a chance to see it, then not see it! The waning gibbous Moon passes in front of magnitude 5.7 Uranus this night, occulting the planet for about an hour around midnight. Exact times will vary with location. Seeing the planet reappear from behind the dark limb of the Moon, as shown here, will be the easiest sighting, but a telescope will be essential.
October 21 — Orionid Meteor Shower Peaks
With both the Perseids and Geminids mooned out this year, the weaker but reliable Orionids remain as perhaps the best meteor shower of 2022. The meteors (expect only about 10 per hour) all appear to radiate from northern Orion, which doesn’t rise until just before midnight. Mars shines bright above the radiant point.
October 25 — Partial Solar Eclipse for Europe
While my list is aimed at North American stargazers, I should mention the partial eclipse of the Sun (there are no total solar eclipses this year) that observers across parts of Asia, Africa, Europe and the U.K. (as shown above) can see.
At maximum eclipse from Siberia about 86% of the Sun’s disk will be covered. No part of the eclipse is visible from North America. For details, see the page at EclipseWise.com.
October 30 — Mars Begins Retrograde Motion
Mars stops its eastward motion this night and begins to retrograde westward for the next two months centred on the date of opposition, December 7. It then stops retrograding and resumes its prograde motion on January 12, 2023. Naked-eye Mars watchers can follow the changing position of Mars easily, using the stars of Taurus, including yellowish Aldebaran below, as a guide.
The second total lunar eclipse of 2022 brings a red Moon to the skies over western North America.
November 8 — Total Eclipse of the Moon
In a mirror-image of the May eclipse, this eclipse also lasts 85 minutes, but can be seen best from western North America. From the east, the Moon sets at dawn with some portion of the eclipse in progress.
But from the west the Moon is fully eclipsed during the wee hours of November 8, with the Moon sitting west of the winter Milky Way, making for good wide-angle photos.
The Moon sits just a degree west of Uranus during totality. From Asia the eclipsed Moon actually passes in front of the planet for a rare eclipse and occultation combination. We have to be content with seeing the green planet east of the reddened Moon. A telescope with 600mm focal length should nicely frame the pairing.
The total phase of the eclipse begins at 5:16 a.m. EST (3:16 a.m. MST) and ends at 6:41 a.m. EST (4:41 a.m. MST).
For details see Fred Espenak’s EclipseWise site. As above, the dark region on this map does not see any of this lunar eclipse.
November 17 — Leonid Meteor Shower Peaks
As with the Orionids, this is normally a weak shower, but this year we have to be content with watching the weak showers. The waxing crescent Moon shining below Leo (as shown above) shouldn’t hinder observations of the Leonids too much. But with Leo not rising until late, this is another shower that requires a long, late night to observe.
Mars reaches its closest point to Earth since October 2020, with the Moon occulting Mars on peak night.
December 1 — Mars at Its Closest
Mars is closest to Earth this night, at 81 million kilometres away. This is not as close as it was in October 2020 when it was 62 million km away. Its disk then appeared large, at 22.5 arc seconds across. Maximum size on this night is 17.2 arc seconds, still good enough for fine telescope views.
Take the opportunity on every clear night to view Mars, as this is as good as we will see the planet until the early 2030s. As it happens, the most interesting side of Mars, featuring the prominent dark Syrtis Major region and bright Hellas basin (shown above in a simulated telescope view), faces us in North America on closest approach night.
Wide-angle views and photos will also be impressive, with reddish Mars shining brightly at magnitude -1.8 in Taurus with its photogenic star clusters, and near the winter Milky Way.
December 7/8 — Mars at Opposition
This is the night Mars is officially at opposition, meaning it lies directly opposite the Sun and shines at its brightest. As it rises at sunset and into the early evening (as above), it is accompanied by the Full Moon, also at opposition this night, as all Full Moons are.
By midnight (above), the Moon and Mars lie due south high in the sky. If you can keep warm and keep an eye on Mars over this long night of opposition, you’ll see surface features on Mars change as the planet rotates, bring new areas into view, with the fork-shaped Sinus Meridiani region rotating into view as triangular Syrtis Major rotates out of sight.
December 7 — Moon Occults Mars
This is very rare! On opposition night, not only does the Full Moon appear close to Mars, it actually passes in front of it during the early evening for North America. The occultation lasts about an hour, and exact times will vary with location. Binoculars will show the event, as will even the naked eye. But the best view will be through a telescope (as above), where you will be able to see the edge of the Moon cover Mars over about half a minute. Ditto on the reappearance. This is an event worth traveling to seek out clear skies if needed.
December 13-14 — Geminid Meteor Shower Peaks
The most prolific meteor shower of the year peaks with a waning gibbous Moon rising about 10 p.m. local time (as above), lighting the sky for the rest of the night. But the early evening is dark, and with Gemini just rising we might see some long Earth-grazing fireballs from the Geminids. So certainly worth a watch on a cold December night.
December 21 — Solstice at 4:48 p.m. EST
Winter officially begins for the northern hemisphere, summer for the southern, as the Sun reaches its most southerly position below the celestial equator. The Sun rises farthest to the southeast and sets farthest to the southwest, and the length of daylight is at its minimum.
December 24 — Inner Planets at Dusk
On Christmas Eve the waxing crescent Moon joins Mercury and Venus low in the southwest evening twilight. Mercury is three days past its greatest elongation, so is easier to see than usual, though it will be three and a half magnitudes fainter than magnitude -3.9 Venus.
December 28 — Mercury and Venus in Conjunction
This evening, descending Mercury passes 1.5° above Venus, now ascending into the evening twilight sky. Venus is just beginning what will be a spectacular evening appearance for early 2023, featuring close conjunctions with Saturn (on January 22, 2023) and Jupiter (on March 1, 2023).
It’s been over 10 years since I’ve last had the luxury of observing an eclipse of the Moon from the comfort of home. Once again, a chase was needed.
During the post-midnight wee morning hours, the Moon was set to once again pass through the Earth’s shadow, this time presenting us with a deep partial eclipse, with 97% of the Full Moon’s disk immersed in the umbra and deep red.
Every lunar eclipse I’ve seen from Alberta since December 2010 I’ve had to chase to find clear skies. While the chases were all successful, this time I was hoping to stay home and enjoy the eclipse without a long drive to seek clear skies, and to then employ a telescope to shoot the Moon in close-up. In the days before the eclipse, the forecasts changed daily.
On the day before the eclipse, things looked bad, with high clouds forecast for home.
It looked like a trip to north-central Alberta was warranted, perhaps to Wainwright. But rather than book a motel, I decided to wait to see if the forecast might improve. And sure enough it did.
By the morning of eclipse day, prospect for clear skies from home looked better Or perhaps a short drive east would suffice. With luck!
But by the evening of the eclipse, clouds were not cooperating. The actual views from satellites showed lots of cloud over my area (as the view out the door confirmed!), and it didn’t look like the clouds were going away.
But as the previous forecasts called for, clear skies were to be found to the north. So at 11:30 pm, with the eclipse starting in less than an hour, I packed up the car and headed north to as far as I could get — and hopefully as far as I need to get — to be assured of clear skies.
It worked! The eclipse was well underway as I made my way north, stopping to check its progress and the state of the clouds. As expected, about 90 minutes north I drove out from under the clouds you can see to the south in the photo above, where I had come from.
I chose a side road and pull off near Rowley, Alberta. I had enough time to set up three cameras, two on polar-aligned trackers to take longer, wide-field images of the Moon amid the stars, plus the static camera for the selfies.
The red Moon below the blue Pleiades was the unique sight at this eclipse. It can only happen if an eclipse occurs in mid-November and that won’t happen for another 19 years, on November 18, 2040, in a total eclipse visible only from the eastern hemisphere.
After some mid-eclipse equipment woes — a tracker deciding to come loose from the tripod, and a lens that refused to focus — I also took some wider shots of the Moon among the stars of Taurus.
Despite writing an extensive blog on how to shoot this eclipse, it did prove to be more of a challenge than I had anticipated. The portion of the Moon outside the umbra, even at mid-eclipse, remained very bright, and overexposed and flared in the frames with long enough shutter speeds to record the stars. A full total eclipse is easier to shoot!
However, I can count this eclipse chase as a success. Of all the total (or near total in this case) lunar eclipses visible from my area of the world since 2001, I’ve seen them all. But almost all required a chase.
Will that be the case next year? We have two total lunar eclipses in 2022: on May 15 (with the Moon rising at eclipse time as seen from here in Alberta), and again six lunar cycles later on the morning of November 8, 2022, which is 12 lunar cycles after this most recent eclipse. We are in the middle of a nice run of 4 lunar eclipses, three total and one near-total.
I present the final cut of my eclipse music video, from the Teton Valley, Idaho.
I’ve edited my images and videos into a music video that I hope captures some of the awe and excitement of standing in the shadow of the Moon and gazing skyward at a total eclipse.

The video can be viewed in up to 4K resolution. Music is by the Hollywood session group and movie soundtrack masters, Audiomachine. It is used under license.
Never before have I been able to shoot a total eclipse with so many cameras to capture the scene from wide-angles to close-ups, in stills, time-lapses, and videos, including 4K. Details on the setup are in the caption for the video on Vimeo. Click through to Vimeo.
I scouted this site north of Driggs, Idaho two years earlier, in April 2015. It was perfect for me. I could easily set up lots of gear, it had a great sightline to the Grand Tetons, and a clear horizon for the twilight effects. And I had the site almost to myself. Observing with a crowd adds lots of energy and excitement, but also distraction and stress. I had five cameras to operate. It was an eclipse experience I’ll likely never duplicate.
If you missed this eclipse, you missed the event of a lifetime. Sorry. Plain and simple.
If you saw the eclipse, and want to see more, then over the next few years you will have to travel far and wide, mostly to the southern hemisphere between now and 2024.
But on April 8, 2024 the umbral shadow of the Moon once again sweeps across North America, bringing a generous four minutes of totality to a narrow path from Mexico, across the U.S., and up into eastern Canada.
It will be the Great North American Eclipse. Seven years to go!
However, while you can read all about how to shoot the eclipse, nothing beats actually shooting to ensure success. But how do you do that, when there’s only one eclipse?
Here are my “Top 10” suggestions:
Wide-Angle Shots – Shoot a Twilight Scene
The simplest way to shoot the eclipse is to employ a camera with a wide lens running on auto exposure to capture the changing sky colors and scene brightness.
Auto Exposure Check in Twilight
If you intend to shoot wide-angle shots of the eclipse sky and scene below, with anything from a mobile phone to a DSLR, practice shooting a time-lapse sequence or a movie under twilight lighting. Does your camera expose properly when set to Auto Exposure? If you are using a phone camera, does it have any issues focusing on the sky? How big a file does a movie create?
With Telephotos and Telescopes – Shoot the Filtered Sun
The toughest techniques involve using long lenses and telescopes to frame the eclipsed Sun up close. They need lots of practice.
Framing and Focusing
You’ll need to have your safe and approved solar filter purchased (don’t wait!) that you intend to use over your lens or telescope. With the filter in place, simply practice aiming your lens or telescope at the Sun at midday. It’s not as easy as you think! Then practice using Live View to manually focus on the edge of the Sun or on a sunspot. Can you get consistently sharp images?
Exposures of the filtered Sun will be the same as during the partial phases, barring cloud or haze, as above, that can lengthen exposure times. Otherwise, only during the thin crescent phases will shutter speeds need to be 2 to 3 stops (or EV steps) longer than for a normal Sun.
With the camera aimed away from the Sun (very important!), perhaps at a distant landscape feature, practice removing the filter quickly. Can you do it without jarring the camera and bumping it off target? Perhaps try this on the Moon at night as well, as it’s important to also test this with the camera and tripod aimed up high.
Ease of Use
With the Sun up high at midday (as it will be during the eclipse from most sites), check that you can still look through, focus, and operate the camera easily. Can you read screens in the bright daylight? What about once it gets darker, as in twilight, which is how dark it will get during totality.
If you are using an untracked tripod, check how much the Sun moves across your camera frame during several minutes. For videos you might make use of that motion. For still shots, you’ll want to ensure the Sun doesn’t move too far off center.
Aligning Tracking Mounts
If you plan to use a motorized equatorial mount capable of tracking the sky, “Plan A” might be to set it up the night before so it can be precisely polar aligned. But the reality is that you might need to move on eclipse morning. To prepare for that prospect, practice roughly polar aligning your mount during the day to see how accurate its tracking is over several minutes. Do that by leveling the mount, setting it to your site’s latitude, and aiming the polar axis as close as you can to due and true north. You don’t need precise polar alignment to gain the benefits of a tracking mount – it keeps the Sun centered – for the few minutes of totality.
Telephotos and Telescopes – Shoot Full Moon Closeups
Shoot the Full Moon around July 8 or August 7. If you intend to use Auto Exposure during totality, check how well it works on the Full Moon. It’s the same brightness as the inner corona of the Sun, though the Moon occupies a larger portion of the frame and covers more metering sensor points. This is another chance to check your focusing skill.
Telescopes and Telescopes – Shoot Crescent Moon Closeups
Shoot the waxing crescent moon in the evening sky during the last week of June and again in the last week of July. Again, test Auto Exposure with your camera in still or movie mode (if you intend to shoot video) to see how well the camera behaves on a subject with a large range in brightness. Or step through a range of exposures manually, from short for the bright sunlit crescent, to long for the dark portion of the Moon lit by Earthshine. It’s important to run through your range of settings quickly, just as you would during the two minutes of totality. But not too quickly, as you might introduce vibration. So …
In the resulting images, check for blurring from vibration (from you handling the camera), from wind, and from the sky’s east-to-west motion moving the Moon across the frame, during typical exposures of 1 second or less.
By practicing, you’ll be much better prepared for the surprises that eclipse day inevitably bring. Always have a less ambitious “Plan B” for shooting the eclipse simply and quickly should a last-minute move be needed.
However, may I recommend …
For much more detailed advice on shooting options and techniques, and for step-by-step tutorials on processing eclipse images, see my 295-page eBook on the subject, available as an iBook for Apple devices and as a PDF for all computers and tablets.
The most spectacular sight the universe has to offer is coming to a sky near you this summer.
On August 21 the Moon will eclipse the Sun, totally!, along a path that crosses the continental USA from coast to coast. All the details of where to go are at the excellent website GreatAmericanEclipse.com.
If this will be your first total solar eclipse, you might want to just watch it. But many will want to photograph or video it. It can be easy to do, or it can be very complex, for those who are after ambitious composites and time-lapses.
To tell you how to shoot the eclipse, with all types of cameras, from cell phones to DSLRs, with all types of techniques, from simple to advanced, I’ve prepared a comprehensive ebook, How to Photograph the Solar Eclipse.
It is 295 pages of sage advice, gathered over 38 years of shooting 15 total solar eclipses around the world.
The book is filled with illustrations designed specifically for the 2017 eclipse – where the Sun will be, how to frame the scene, what will be in the sky, how the shadow will move, where the diamond rings will be, what lenses to use, etc.
Here are a few sample pages:
I cover shooting with everything from wide-angle cameras for the entire scene, to close-ups with long telephotos and telescopes, both on tripods and on tracking mounts.
I cover all the details on exposures and camera settings, and on focusing and ensuring the sharpest images. Most bad eclipse pix are ruined not by poor exposure but poor focus and blurry images – the Sun is moving!
A big chapter covers processing of eclipse images, again, from simple images to complex stacks and composites.
For example, I show how to produce a shot like this, from 2012, combining a short diamond ring image with a long-exposure image of the corona.
A final chapter covers “what can go wrong!” and how to avoid the common mistakes.
The ebook is available on the Apple iBooks Store for Mac and iOS devices. This version has the best interactivity (zoomable images), higher quality images (less compression), and easiest content navigation.
However, for non-Apple people and devices, the ebook can also be purchased directly from my website as a downloadable PDF, which has embedded hyperlinks to external sites.
I think you’ll find the ebook to be the most comprehensive guide to shooting solar eclipses you’ll find. It is up to date (as of last week!) and covers all the techniques for the digital age.
Many thanks, and clear skies on August 21, wherever you may be in the shadow of the Moon!
My free Amazing Sky Calendar for 2017 is now available for download! Plan your astronomical year!
Once again, I have prepared a free 12-month Calendar listing loads of celestial events, Moon phases, highlighted space events, and with small charts to show what’s happening in the sky for the coming year. Plus a set of my favourite images from 2016.
On Sunday, September 27 the Moon undergoes a total eclipse, the last we’ll see until January 2018.
This is a sky event you don’t want to miss. Whether you photograph it or just enjoy the view, it will be a night to remember, as the Full Moon turns deep red during a total eclipse.
Note — For this article I’m giving times and sky directions for North America. For Europe the eclipse occurs early in the morning of September 28, as the Moon sets into the west. But for here in North America the timing could not be better. Totality occurs in the evening of Sunday, September 27 as the Moon rises into the east.
A total lunar eclipse occurs when the Moon — and it can only be Full — passes through the shadow cast into space by Earth. The Sun, Earth and Moon are in near-perfect alignment.
All total eclipses of the Moon consist of 3 main parts:
• The initial partial eclipse occurs as the Moon slowly enters the dark central portion of our planet’s shadow, the umbra. This lasts about an hour.
• Totality begins as the entire disk of the Moon is within the umbra. For this eclipse, totality lasts a generous 72 minutes.
• Totality ends as the Moon emerges from the umbra to begin the final partial eclipse lasting another hour.
WHERE TO SEE IT
All of North America, indeed most of the western hemisphere, can see this eclipse. In North America, the farther east you live on the continent the later in your evening the eclipse occurs and the higher the Moon appears in the southeast.
For example, in the Eastern time zone, totality begins at 10:11 p.m. EDT and ends at 11:23 p.m. EDT, with mid-totality is at 10:47 p.m. EDT with the Moon about 35 degrees up, placing it high in the southeast sky for southern Ontario, for example.
For me in the Mountain time zone, the total eclipse begins at 8:11 p.m. MDT and ends at 9:23 p.m. MDT, with mid-totality is at 8:47 p.m. MDT, with the Moon just 13 degrees up in the east from here in southern Alberta. From my time zone, and from most location in the Rocky Mountain regions, the Moon rises with the initial partial phases in progress.
For locations on the west coast viewers miss most of the partial eclipse phase before totality. Instead, the Moon rises as totality begins, making for a more challenging observation. Viewers on the coast will need clear skies and a low horizon to the east, but the reward could be a beautiful sight and images of a red Moon rising.
This eclipse of the Moon is the last in a series of four total lunar eclipses that occurred at six-month intervals over the last two years. We won’t enjoy another such “tetrad” of total lunar eclipses until 2032-33.
But this eclipse is unique in that it also coincides with the annual Harvest Moon, the Full Moon closest to the autumnal equinox. Harvest Moons are known for their orange tint as they rise into what is sometimes a dusty autumn evening.
But what is making internet headlines is that this Full Moon is also the year’s “supermoon,” the Full Moon of 2015 that comes closest to Earth. In recent years these “perigee” Full Moons have been dubbed “supermoons.”
Call it what you will, it does make this Full Moon a little larger than usual, though the difference is virtually impossible to detect by eye. And it makes little difference to the circumstances or appearance of the eclipse itself.
HOW TO SEE IT
Just look up! You can enjoy the eclipse with the unaided eye, and even from within city limits.
Unlike eclipses of the Sun, the eclipsed Moon is perfectly safe to look at with whatever you wish to use to enhance the view. The best views are with binoculars or a telescope at low power.
Look for subtle variations in the red colouring across the disk of the Moon, and even tints of green or blue along the dark edge of the Earth’s advancing or retreating shadow during the partial phases.
If you can, travel to a dark site to enjoy the view of the stars and Milky Way brightening into view as the Full Moon reddens and the night turns dark.
HOW TO SHOOT IT
1. On A Tripod
The easiest method is to use a camera on a tripod, with a remote release to fire the shutter and prevent vibration from blurring the image. What lens you use will depend on how you wish to frame the scene and how high the Moon is in your sky.
From eastern North America you’ll need a wide-angle lens (14mm to 24mm) to frame the eclipsed Moon and the ground below. The Moon will appear as a small red dot.
While you can shoot the Moon with longer focal lengths it takes quite a long lens (>300mm) to really make it worthwhile shooting just the Moon itself isolated in empty sky. Better to include a landscape to put the Moon in context, even if the Moon is small.
From western North America the lower altitude of the Moon allows it to be framed above a scenic landscape with a longer 35mm to 50mm lens, yielding a larger lunar disk.
From the west coast you could use a telephoto lens (135mm to 200mm) to frame the horizon and the eclipsed Moon as it rises for a dramatic photo.
Use Live View (and zoom in at 10x magnification) to manually focus on the horizon, distant lights, or bright stars. The Moon itself my be tough to focus on.
Exposures will depend on how bright your sky is. Use ISO 400 to 800 and try metering the scene as a starting point if your sky is still lit by twilight. Use wide lens apertures (f/4 to f/2) if you can, to keep exposures times as a short as possible.
The apparent motion of the Moon as the sky turns from east to west will blur the image of the Moon in exposures lasting more than a few seconds, especially ones taken with telephoto lenses.
The maximum exposure you can use before trailing sets in is roughly 500 / lens focal length.
2. On a Tracker or Equatorial Mount
If you can track the sky using a motorized tracker or telescope mount, you can take exposures up to a minute or more, to record the red Moon amid a starry sky.
For this type of shot, you’ll need to be at a dark site away from urban light pollution. But during totality the sky will be dark enough that the Milky Way will appear overhead. Use a wide-angle lens to capture the red Moon to the east of the summer Milky Way.
3. Through a Telescope
The most dramatic closeups of the eclipsed red Moon require attaching your camera body (with its lens removed) to a telescope. The telescope becomes the lens, providing a focal length of 600mm or more, far longer than any telephoto lens most of us own.
You’ll need the appropriate “prime focus” camera adapter and, to be blunt, if you don’t have one now, and have never shot the Moon though your telescope then plan on shooting with another method.
But even if you have experience shooting the Moon through your telescope, capturing sharp images of the dim red Moon demand special attention.
The telescope must be on a motorized mount tracking the sky, preferably at the “lunar,” not sidereal, drive rate. Focus on the Moon during the partial phases when it is easier to focus on the bright edge of the Moon.
Exposures during totality typically need to be 5 to 30 seconds at ISO 800 to 3200, depending on the focal ratio of your telescope. Take lots of exposures at various shutter speeds. You have over an hour to get it right!
I’d suggest attempting time-lapses only if you have lots of experience with lunar eclipses.
Exposures can vary tremendously over the partial phases and then into totality. Any time-lapse taken through a telescope, or even with a wide-angle lens, will require a lot of manual attention to ensure each frame is well-exposed as the sky and Moon darken.
However, even if you do not get a complete set of frames suitable for a smooth, continuous time-lapse, selected frames taken every 5 to 10 minutes may work well in creating a multiple-exposure composite (as above), by layering exposures later in Photoshop.
Whatever method – or methods — you use, don’t get so wrapped up in fussing with cameras you forget to simply enjoy the eclipse for the beautiful sight it is.
This is the last total eclipse of the Moon anyone on Earth will see until January 31, 2018. So enjoy the view of the deep red Moon in the autumn sky.
My 2-minute music video looks back at some of the celestial highlights of 2013, in images and videos I captured.
Some of the events and scenes I show were accessible to everyone who looked up. But some required a special effort to see.
• In 2013 we had a couple of nice comets though not the spectacle hoped for from Comet ISON.
• Chris Hadfield became a media star beaming videos and tweets from the Space Station. We on Earth could look up and see his home sailing through the stars.
• The sky hosted a few nice conjunctions of planets, notably Mars, Venus and Jupiter in late May.
• The Sun reached its peak in solar activity (we think!) unleashing solar storms and some wonderful displays of northern lights.
• Locally, record rain storms in Alberta unleashed floods of devastating consequences in June, with a much publicized super moon in the sky.
• For me, the summer proved a productive one for shooting the “star” of the summer sky, the Milky Way.
• But the year-end finale was most certainly the total eclipse of the Sun on November 3. Few people saw it. I did, from a ship in the Atlantic Ocean. The video ends with that sight and experience, the finest the sky has to offer.
I hope you enjoy this music video mix of time-lapse, real-time video and still images, shot from Alberta, New Mexico and from the Atlantic.
You can watch a better quality version of this video at my Vimeo channel.
Following any total solar eclipse it’s traditional to look for the crescent Moon as it returns to the evening sky.
This was the view on November 6, three days after Sunday’s total solar eclipse when the waxing Moon was near Venus, with both high in our tropical sky as we finish our sail across the Atlantic. As I write this, we have just sighted the lights of Barbados off the port side as we round the north end of the island. It’s our first sighting of any other sign of civilization in two weeks, since we left the Canary Islands.
This view is from the next night, November 7, with the Moon higher and well above Venus, set amid the square rigged sails of the Star Flyer clipper ship.
It’s been a fabulous voyage across the Atlantic, with largely calm seas and beautiful weather on most days.
For many of us on board the spvStar Flyer, last Sunday’s eclipse on the Atlantic Ocean will be remembered as much for the rainbows as for the eclipse.
The main image above shows the spectacular and classic double rainbow that appeared before the partial phases began, demonstrating the rain showers and unsettled weather we passed through on eclipse day.
The low rainbow shown here appeared well into the partial phase, with 60 to 70 % of the Sun covered, so the source of light is considerably smaller than usual for a rainbow. You can see multiple bands of colour on the inner edge of the inner bow. Seeing this appear and rushing over to shoot it was another exciting moment in a hectic morning of roller coaster emotions. As this bow appeared, the light was beginning to drop rapidly toward the final spectacle of totality.
Today on my drive north to the path of the November 14 total eclipse in Australia, I crossed the Tropic of Capricorn and am now officially in the tropics.
This is one of the many monuments that the demarcates this important line around the world, all located at 23.5° south latitude (or thereabouts). This one is in Rockhampton, Queensland. It’s actually at 23° 23′ 59″ S but that’s close enough for tourists. For photos of other Tropic of Capricorn monuments see Wikipedia’s page.
The Tropic of Capricorn is one of the world’s four main lines of latitude defined by the tilt of the Earth: The Arctic and Antarctic Circles at 66.5° N and S, and the Tropics of Cancer and Capricorn, at 23.5° N and S. The names for the Tropic lines come from the two constellations where the Sun used to be located millennia ago on the June and December solstices: Cancer and Capricornus. The precession motion of the Earth’s axis has since moved the Sun into Gemini and Sagittarius on those key annual dates.
The Tropic of Capricorn is the southernmost latitude on our planet where the Sun can appear directly overhead at the zenith, and then only on one day, the December solstice. I was here close to that date a few years ago and can attest to the lack of shadows at “high noon” at solstice on a Tropic line.
The zone on Earth between the two Tropic lines, between 23.5° N and 23.5° S, is of course called the Tropics. While the Sun may not always be overhead in the tropics it certainly is always high at mid-day. And hot!
Next stop: Magnetic Island, named by James Cook in 1770 as he thought the island was affecting his compass in strange ways.
This was the kind of eclipse chasing I like — just to the end of my driveway … to shoot the partial eclipse of the Moon before dawn on June 4.
While the car is all packed with gear for a possible flight or cross-country chase to clear skies to catch the Venus transit tomorrow, the lunar eclipse required no travel at all. Not that I was going to make too much effort at 4 am!
While some clouds got in the way, a clear hole opened up at the right time, with the remaining clouds adding a photogenic touch. I’m hoping to be as lucky for the transit!
This was just a partial lunar eclipse, with only 37 percent of the Moon immersed in the Earth’s umbral shadow at mid-eclipse, shortly after this image was taken. Even so, some of the reddening of the shadowed portion of the Moon’s disk does show up here.
I shot this from southern Alberta with a Canon 60Da and an 18-200mm lens at 115mm to frame the Moon and prairie landscape.
This was the first significant solar eclipse in many years that I did not travel to. For the May 20, 2012 eclipse I was content to stay at home on the sidelines and take in the partial eclipse of the Sun.
From Calgary, the Moon covered about 62% of the Sun at mid-eclipse, which this shot captures, taken at maximum eclipse for us. Here, a big sunspot group is just being uncovered by the passing Moon. Having lots of spots on the Sun this day made the partial eclipse all the more interesting, though still no comparison to the annular eclipse visible over the spectacular landscapes of the southwestern U.S.
I would have been there, in the Moon’s ant-umbral shadow, had it not been for the fact that at home I am very much involved in the opening of a new planetarium and digital dome theatre at the science centre, TELUS Spark, where I work. This is a milestone event in one’s life, one I’ve had the privilege of experiencing twice before, in 1984 in Edmonton with the opening of its new science centre and planetarium, and in 1996 when we converted the old Calgary Centennial Planetarium into a then state-of-the-art tilt-dome theatre. Oddly coincidental, I missed seeing the May 15, 1984 annular eclipse in the SE United States due to the imminent opening of the Edmonton theatre. History repeats itself — a Saros cycle of science centres perhaps?
For this eclipse we conducted a public viewing session and managed to grab excellent views once clouds cleared away before mid-eclipse. Eclipse anxiety was running high leading up to and through the initial minutes of the eclipse as it looked like clouds were going to skunk us. But wonder of wonders, the sky cleared and the eclipsed Sun was revealed, to my great relief. Missing the annular eclipse is bad enough; I didn’t want to miss the partial eclipse, too!
Now, we just need clear skies on June 5 for the transit of Venus.
