Pretty sure I saw some of these airglow ripples when I went outside to look at stars in the middle of the night last night: https://spaceweather.com/

It wasn't quite like auroras I've seen (although I'm still quite new at seeing auroras regularly).

Also, we've gotten to the point in the year at my latitude where there is true darkness for a bit in the middle of the night, and no sunlit satellites! That was extremely enjoyable to see the Milky Way with NO STUPID SATELLITES crawling across it.
