2410_1468 Night Sky & SAR Arc

Is this a SAR arc? It appears to be. They appear during strong geomagnetic storms, but they aren't Auroras. Here's a good explanation: spaceweatherarchive.com/2021/11/22/3308/

I shot this from near the same location as the first image posted in this set, facing in the opposite direction, approximately south. The moon, which looks full here, was only half-lit, and slowly setting. The clouds were moving toward and over me. The Aurora was directly behind me. And that SAR band, very faint, yet visible to the naked eye, and much more intense as seen by my camera's sensor. At the time I thought it was part of the Aurora display. But no. This is "heat energy leaking into the upper atmosphere from Earth's ring current system." Check out the article for a more detailed description.

Two more night shots to come, and then we'll return to Earth for a while...
