The Great Red Aurora


On November 11, 2025 the sky erupted with a swath of red Northern Lights seen over much of North America.

It is rare when those living at southerly latitudes can see Northern Lights. Instead of having to travel north to Arctic sites, the aurora comes south to them. That’s what happened on November 11, 2025 when one of the largest solar storms in recent years brought the aurora down over much of the North America.

This was the latest in a set of wonderful aurora shows we’ve enjoyed in the last two years, as the Sun reached the peak of its 11-year cycle of activity.

As I show below, the apps and indicators were registering extreme conditions, with the “Kp Index” peaking at 8 out of a maximum of 9, and the auroral “Ovation” oval lighting up red, indicating a major geomagnetic storm was underway. In the lingo of the local Alberta Aurora Chasers Facebook group, it was most definitely a “pants on” night!

The source of the storm was two major flares on the Sun in quick succession. In only a day the high-speed “coronal mass ejections” they had unleashed reached Earth and lit up the sky.

As a result the ring of aurora borealis which usually circles the Arctic moved down over southern Canada and the northern United States. I was under that ring of lights!

This is a blend of two exposures, for sky and ground, both 8 seconds at f/2.8 with the TTArtisan 11mm full-frame fish-eye lens on the Canon R5 at ISO 1600.

As it got dark this night, large swaths of red were easily visible to the eye, especially to the northwest as above, and below.

A single 5-second exposure at f/2.8 with the TTArtisan 11mm lens on the Canon R5 at ISO 1600.

Early on a large curtain of red extended across the sky, from northwest to southeast. It is rare to see bright reds with the eye, and unusual to see the reds so extensive and sky-spanning.

This 360º panorama is a stitch of 6 segments, 60º apart, each 5-second exposures at f/2.8 with the TTArtisan 11mm full-frame fish-eye lens on the Canon R5 at ISO 1600, and in landscape orientation.

The reds are mostly from oxygen atoms, but can also come from nitrogen molecules, which require the input of a lot of energy to get excited and glow! They certainly were this night.

The reds mixed with the more common green light from oxygen to produce shades of yellow and orange, and with blues from nitrogen to produce vivid pinks and magentas. While the eye could see some of these subtle colours, a camera (with its longer exposure and wider aperture lens compared to the human eye) was best for picking up the full range of what this show had on display.

This 360º panorama is a stitch of 10 segments, 36º apart, each 4-second exposure at f/2.8 with the Laowa 10mm rectilinear wide-angle lens on the Nikon Z8 at ISO 1600, and in portrait orientation.

The panorama above taken about 2 hours after the previous all-sky scene, shows a quieter aurora but still with curtains covering the sky and converging to the “magnetic zenith,” a little south of the point straight overhead.

Such an all-sky show of aurora is among the sky’s finest spectacles.

A real-time video with the Nikon Z6III at ISO 25600 and Viltrox 16mm lens at f/1/8.

In the video above taken early in the evening I pan around the horizon over the full 360º to take in the scene much as the eye did see it. Video uses shorter exposures more like the eye does. I narrate the video at the camera.

When the aurora covers the sky it’s hard to take it all in and capture it on camera. The 10mm ultra-wide lens I used for the images above sweep up well past the zenith to show the converging curtains, forming shapes that kept changing by the minute.

In the video below I used the same lens with the camera turned to portrait orientation to create a “vertical video,” again narrated at the camera. It shows how the aurora was changing, but slowly this night. It did not have the rapid dynamics I’ve seen with other bright displays, despite the obvious high energies involved here to excite the reds.

Again, this real-time video captures the scene much as the unaided eye saw it. I’ve not processed either of these real-time videos, other than what the camera itself did.

This is a panorama of 12 segments, each 1 second at f/1.8 with the Viltrox 16mm lens on the Nikon Z6III at ISO 1600. Stitched in Adobe Camera Raw.
This is a stitch of 6 segments, 60º apart, each 4-second exposure at f/2.8 with the TTArtisan 11mm full-frame fish-eye lens on the Canon R5 at ISO 1600, in landscape orientation. Stitched in PTGui.

On a night like this, I try to shoot not only single still images and videos, but also multi-image panoramas, such as the circular images earlier and these two rectangular “panos” above. Both cover a full 360º in width but don’t go up to the zenith.

Again, they record the range of colours that were on show on this Kp8 night, which were more visible and extensive than usual for an all-sky display.

I also shot two time-lapse sequences. These form the main visuals for this edited music video I produced around the time-lapses.

The link takes you to my Vimeo channel to watch the video. Do enlarge it to full screen!

I also always try to take some selfies at every great aurora show, with me often lit just by aurora light! They’re fun to use for talks and “bio pix.”

This is a single 4-second exposure at f/2.8 with the Laowa 10mm lens on the Nikon Z8 at ISO 1600.

As a final bonus this night, one of the fish-eye lens time-lapse frames happened to capture a bright meteor. You see it briefly in a flash in the music video above, but below is the single frame.

A single 4-second exposure at f/2 with the TTArtisan 7.5mm circular fish-eye lens on the Nikon Z8 at ISO 1600. Taken as part of a 780-frame time-lapse.

Because it is streaking away from the constellation of Taurus, this is likely a member of the annual Taurid meteor shower which was in its final nights of the long period it is active in late October and early November. In fact, there are two Taurid showers, Northern and Southern, active at once and coming from similar spots in Taurus. They are known to produce bright fireballs and this was certainly one!

While the Sun is now in the downward slope of its cycle, coming off “solar max” last year, we may still see more major storms and aurora shows like this. Historically, the biggest solar flares and aurora displays often occur in the 2 or 3 years after solar maximum.

So stay tuned! The sky may still light up red with Northern Lights!

Chasing the Red Moon to the Mountains


It took a last-minute chase, but I managed to capture the total eclipse of the Moon on March 14, 2025.

It would not be an eclipse without a chase. Solar eclipses of the total kind almost always involve travel, often to exotic locales around the world. But total lunar eclipses come to you, as they can be seen from an entire hemisphere of the planet.

Except there’s one problem — clouds! Over the last decade since 2014, of the eight total lunar eclipses (TLEs) I was home in Alberta for, I had to chase into clear skies for all but one. A recounting of one such chase from January 2019 is here.

Only for the TLE before this most recent (on November 8, 2022) was I able to stay home to watch it. Though in that case a snowstorm the day before made the roads and travel poor, so I had to stay home. I recounted that eclipse story here. You’ll find links to my other lunar eclipse stories below.

Once again, for the March 13/14, 2025 TLE, weather prospects looked poor. Not just in my area but in many regions of the continent. But there was hope!

Astrospheric and Environment Canada cloud forecast + Moon information

The forecast cloud cover showed home to be hopeless. But a clear area was supposed to be open in southwestern Alberta, marked by the red circle above. That’s Waterton Lakes National Park, just on the US border. It’s a favourite place of mine for nightscape photography anyway (see my blog from this past summer here).

The chart above from the app Astrospheric shows the clear hole, and the dark blue on the time-line indicates the period with no clouds. Note how it coincides with the wavy line below which shows Moon altitude, with the orange and red regions indicating when the eclipse would take place. Looks good! So I made my plan to chase.

I knew the area well enough to know the site would be a good one for the eclipse, and the Moon’s location to the south. But it pays to check. I use The Photographer’s Ephemeris as my main photo planning app.

TPE Plot of Sightlines

It showed the sightline toward the Moon during the eclipse as straight down Upper Waterton Lake. My chosen spot was on the lakeside Waterton Avenue, where I could set up both the wide-angle camera and a telescope without having to heft gear any distance. Winter road closures also limited my site choices. Indeed, in winter the Park is quiet, with only a few hotels and restaurants open, and many businesses boarded up.

TPE 3D Simulation

Switching to the companion app TPE 3D (above) showed a preview of the landscape and the Moon’s position in the sky relative to the scene below.

Compare the simulation to the real thing below! Pretty accurate, except for the scattered clouds that drifted through.

This is a blend of separate images for the sky and ground: a stack of two untracked images for 60 seconds each for the ground, then a third exposure for the sky and untrailed stars, taken immediately afterwards with the tracker motor on, for 30 seconds, all with the Canon RF15-35mm lens wide-open at f/2.8 and at 20mm, on the Canon R5 at ISO 1600. Separate shorter tracked exposures of 15, 8 and 4 seconds blended in kept the lunar disk from overexposing, showing it more as the eye saw it.

The above image is a blend of tracked exposures for the Moon and sky, with untracked exposures for the ground. I shot them just before mid-totality at 1 am MDT. That image was second in priority. First, was a panorama. That result is below.

This is a panorama of four segments at 30º spacing, taken in two passes: first untracked for 30 seconds each, then a second pass immediately afterwards with the tracker motor on, also for 30 seconds each, all with the Canon RF15-35mm lens wide-open at f/2.8 and at 20mm, on the Canon R5 at ISO 1600, with the camera in landscape orientation. Separate shorter exposures of 15s, 10s, 5s and 2.5s at ISO 400 were blended in to preserve the lunar disk more as the eye saw it.

I shot this scene just as totality began, to ensure I got it. While the Moon was in clear sky before totality during the partial phase, sure enough as the Moon became fully eclipsed, the clouds wafting over the mountains threatened to move in and obscure the view.

Luckily, while they did hide the Moon now and then, they opened up enough for good views and images for a few minutes at a time throughout the eclipse.

For the panorama I processed the image for a more monochromatic look, to resemble the naked-eye view, but with the Moon appearing as a red globe in the sky, the only colour in the scene. (I shot the tracked shots with the MSM Nomad tracker I reviewed here.)

The site proved excellent, but it was a cold night! While the temperature was only just below freezing, the brisk Waterton wind off the lake made it a chilly experience watching the eclipse for two hours. I was actually being hit by ice pellets blowing off the lake.

I decided not to set up the telescope for close-ups; the wide-angle images were the priority anyway from such a scenic spot.

A single untracked 15-second exposure with the RF15-35mm lens at f/2.8 and 17mm on the Canon R5 at ISO 3200.

But I am not complaining. I got the eclipse, once again by chasing to where the weather predictions said it would be clear. The above is my requisite trophy shot.

Had I stayed home I would have been clouded out. Had predictions called for clear skies at home, I would not have made the trip to Waterton to enjoy the eclipse over its wonderful scenery.

The next total lunar eclipse is September 7, 2025, six months after this eclipse. But it is visible from the opposite hemisphere to this one, with no part of that eclipse visible from North America. I will not chase that far for a TLE!

The March 3, 2026 TLE from Alberta

After that, and after a passage of one lunar year (355 days or 12 lunar cycles) since the March 14, 2025 TLE, I have a chance for another total lunar eclipse from home, with western North America favoured. As I preview above, it’ll be an early morning event on March 3, 2026, with the eclipsed Moon setting in the west in the pre-dawn hours.

Sounds like another chase to a mountain site with the red Moon over the Rockies. That’ll be the plan!
