On this morning’s APOD, we get to watch a near-three-minute time-lapse video of auroras over Tromsø, Norway. I’ve never seen an aurora, living at a too-low latitude all my life, though Karla once saw one while at the high ranch one summer. So I’ve never seen the speed of movement. You folks who have seen auroras: How fast do they shift and shimmer?
