December 4, 2025 Auroras

Coleraine, MN.

Nothing fancy here. Just an auroral arc that appeared under a nearly full moon in the evening. I didn't stick around to see any substorm, and the solar wind conditions became a bit less favorable during the night, anyway. This is the picture I took with my cell phone in the middle of snowmaking.
