Following a coronal mass ejection on Monday, tonight's aurora forecast is epic:
Unfortunately, I have an event just outside the Loop that ends around 10. By the time I got home, loaded up the dog, and drove to a place without streetlights, it would be around 1am. So no photos; but maybe I'll see some aurorae when I get home.
We'll see. Fortunately, we have had perfectly clear skies for 4 straight days, with no significant cloud cover forecast until tomorrow afternoon.
Aurorae peak at local midnight, which tonight in Chicago will be 00:38. I'll check around 11pm.
