Auroral Hummingbird over Norway
Is this the largest hummingbird ever? Although it may look like a popular fluttering nectarivore, what is pictured is actually a beautifully detailed and colorful aurora, complete with rays reminiscent of feathers. This aurora was so bright that it was visible to the unaided eye during blue hour -- just after sunset when the sky appears a darkening blue.

The aurora can display in a lot of ways. Often it looks like columns appearing then disappearing like dust catching sunbeams through the blinds. It's the same idea as taking a long exposure of a thunderstorm. The lightning didn't all happen at once.
Where someone posts an image can also depend on community preference and care given to posting in multiple communities.
Also odd to suspect something in a science community is less likely to be real than one in an art community but, all things being even, the skepticism is a bit healthier here i guess.
At the end of the day, this doesn't look unlike a real aurora and the time lapse is also evidenced by the brightly lit hilltop... ... And the stars. And bright unlit areas
