The #aurora from the northern edge of Davis, California. I was barely able to make out the aurora visually (much easier with the camera), so this is the first time I've seen an aurora with my own eyes! 🔭
An image showing the nighttime sky above a flat landscape low in the frame.There are distant mountains on the left, and bright lights on the right. In the rightmost third of the sky there is a reddish-pink diffuse band running vertically, with a greenish area of the sky to the left of the pink band.
