That was the view to the south over center of Greenland a few hours ago: a late afternoon aurora over a blue dusk.
I departed London about four hours before taking this shot, and am writing this in Santa Barbara. According to my little hand-held GPS, we were just above 70° north when I took that shot, or about four degrees north of the arctic circle. The flight as Air New Zealand 1, and that same plane is now en route to Auckland.
We were also inside the auroral oval:
Normally on transatlantic flights between Europe and the U.S., one looks north at the aurora, but in this case I was looking south.
Even after flying millions of miles as a passenger, it still blows my mind what one can see out the window of a plane.
I’ll put up the full series of shots after I get sleep.
