Famed Arctic and aurora photographer Ole C Salomonsen has reported in last hour strange lights over Tromso, Norway. Ole says the sight is the “weirdest stuff I’ve seen”.
I’ve taken the liberty of increasing the brightness of two of the images he posted:

I can’t imaging what this is, but I suspect it’s related to some sort of rocket-borne experiment. But the spatial distribution of the lights is very strange. I assume Ole will update us with time lapse photography in the near future.
