Although I tire of these "prosaic" APODs, I'll ask a question anyway: the Instagram link says this is a 360° panorama, which explains the arc shape of the Milky Way (which naturally follows a great circle on the celestial sphere), the aurora is also seen as an arc here, but is also described as looking like an arc by direct eye view. So I suppose this panorama simply makes the aurora look more like an arc than normal?
