Rising of the Snow Moon & Jupiter


Full Snow Moon over Silver City Panorama #1

Tonight the Full Moon rose paired with Jupiter, in the colourful twilight over Silver City, New Mexico.

Using The Photographer’s Ephemeris app, I scouted out the location last night for the shoot tonight, February 3.

I drove west of Silver City to a viewpoint on Boston Hill overlooking the town east to the rising Moon.

The Full Moon of February has come to be called the “Snow Moon,” appropriate for many parts of the continent now enduring record snowfalls. But here, we enjoyed summer-like temperatures and a decided lack of snow.

The Moon rose into a clear sky accompanied by Jupiter, now 4 days before its annual opposition date. At opposition we pass between the Sun and an outer planet, in this case Jupiter. This puts Jupiter opposite the Sun, so it rises as the Sun sets.

The Full Moon also always lies opposite the Sun, so tonight the Full Moon joined Jupiter in the sky.

To capture the scene I shot several panoramas, each consisting of several segments, to take in the broad sweep of the horizon. The scene above records the pink “Belt of Venus,” created by sunlight lighting the upper atmosphere to the east in the half hour or so after sunset down here on Earth.

Once the sky got darker, Jupiter stood out better, shining to the left of the Moon.

Jupiter is now also closest to Earth and brightest for 2015. It will dominate our eastern sky for the rest of the winter and early spring, eventually shining to the south as night falls in late spring.

Heads Up! – A Picturesque Snow Moonrise


Feb 3 Moon & Jupiter

This Tuesday, Feb. 3, watch the Full “Snow” Moon rise accompanied by the giant planet Jupiter.

Tuesday is Full Moon, the February “Snow Moon” according to some interpretations. Indeed, from most places in North America the Moon will rise over a snow-covered landscape to light the winter night.

This Full Moon is also special because it will pair with bright Jupiter. Both worlds are now at or near “opposition.”

Any Full Moon is always opposite the Sun – that’s why it is fully illuminated by the Sun.

But Jupiter is also near its annual opposition point in its orbit. The official date of opposition is Friday, Feb. 6. On that date Earth passes directly between the Sun and Jupiter – our three worlds lie in a line across the solar system. We are then closest to Jupiter and Jupiter appears opposite the Sun.

Being opposite the Sun, Jupiter rises as the Sun sets. And so will the Full Moon on Tuesday, accompanied by the giant planet now at its brightest for the year.

Look east at sunset. It will be a photogenic sight for the prepared photographer.

But you can also enjoy it with just the unaided eyes or binoculars, as the two worlds will appear about a binocular field apart, 5 degrees.

The double circles on the chart mark the position of the Earth’s shadow, which is always opposite the Sun. You can’t see our shadow out in space – not unless the Full Moon passes through it, which it will on April 4, for a total eclipse of the Moon. More about that in two months.

For now, enjoy the Snow Moon with the Giant Planet.

Snow Moon over the Science Centre


Here’s the Full Moon of February rising over the place I work, the science centre in Calgary, called TELUS Spark.

I took this Tuesday evening, February 7, on the night of what is sometimes called the Snow Moon. I knew the Full Moon would rise in the northeast and worked out, with the help of a useful iPad app, just where to stand on the hill above the science centre to get the Moon rising over the science centre. Though it did take a last minute move of a hundred feet to place the Moon over the front entrance!

The building glows from the light of banks of LEDs that can be programmed to slowly change colour. The parking lot lights are all nicely shielded, as any astronomically friendly place should be, to prevent light spilling upward. The odd structure to the left contains the new digital dome theatre, which opens this spring. The dome screen is being installed this month. The dome will feature a Digistar 4 projection system with two pairs of very high-end Sony 4K video projectors, for interactive star shows and full-dome movies. Maybe even laser shows!

Should be fun!
