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