I’ve still never seen aurora from below, but up here, it’s a frequent show. Last week’s was especially good. See if you can spot Houston, Florida, and the northern lights all in one frame, before we head out across the Gulf and some great lightning storms over South America at sunrise.
Here's a time-lapse of the Sept 30/Oct 1 Kp5-6 aurora from southern Alberta, looking north and covering about 52 minutes from 12:05 am to 12:57 am, with the aurora mostly in a pulsating phase at that time. This is 256 exposures @ 10 seconds each.

The 18-19 September 1941 geomagnetic storm was a solid G5. It was also at G4 level or higher for no less than 27 hours! The Washington Post wrote: "Nature put on one of her most spectacular shows last night when the aurora borealis - northern lights - pierced the sky with white, yellow, green, rose and lavender rays". The photo shows spectacular aurora over Bergenfield, New Jersey. We can only imagine what the colors were like. Photo: Jack Layer, now in the Harry Ransom Center, University of Texas.
