On April 23, 2023 the sky erupted with a massive solar storm, bringing the aurora to millions of people around the word.
On April 23 warnings went out alerting aurora watchers that a solar storm was imminent. And as the sky darkened that night locations all across the Northern and Southern Hemispheres were treated to a great sky show.
When we see this on our phone apps, we know we’ll get a great show. This was the auroral oval, lit up red, as the display was underway at my location in Alberta, Canada.
The strength of the interplanetary field (Bt) was high and the direction of the field (Bz) was well south, all welcome indicators of a superb show.
Sure enough, as it got dark that night, and from my location after the clouds cleared, an aurora was underway covering much of the sky.
The aurora moved south to occupy just the southern half of the sky, but with incredible ribbons crossing from east to west, rippling and pulsating off and on. Seeing patches of aurora pulse off and on and flaming up to the zenith is not uncommon toward the end of a substorm outburst. But this was the first time I can recall seeing pulsating ribbons.
At times, there was a dark ribbon across the sky, as the aurora formed a gap in its curtains, looking like a “dark aurora.”
The view looking straight up is always the most jaw-dropping when an aurora fills the sky. Rays and curtains converge at the magnetic zenith to form a “corona.”
I shot with three cameras, taking stills, time-lapses, and real-time movies. I edited them together here in a music video. Enlarge to full screen to view it. I hope you enjoy it!
With the Sun ramping up in activity, we should get more great shows of Northern – and Southern! – Lights around the world in the next few years,
