Aurora down south
Victoria had it's own aurora last week but I wasn't near enough to Flinders to see it.
The sunspot activity showered particles on the Earth, that excited oxygen atoms high in the atmosphere which emitted a red glow as they fell back to their ground state. Oxygen atoms lower in Earth's atmosphere would glow green.
So here is a photo of the aurora just visible above the horizon near Flinders, our own Flinders, Victoria. Also seen in the photo is the central disk of the Milky Way Galaxy on the left and the large and small Magellanic Cloud galaxies on the right.
The photograph was taken by Alex Cherney.
