The trouble with aurora is, and this is obvious, you have to be awake to see it. Apparently I was premature in my "the aurora season is ending" talk. Last night the earth received a nearly direct hit by a coronal mass ejection (CME) from the sun, igniting lights across Alaska and as far south as Montana, North Dakota, and Washington. It doesn't get dark until about 11pm in Fairbanks now, and I was long in bed by then. This photo of a pinwheel like pattern, with green ribbons spinning off a central blob, was taken back in February during another CME strike.
