Details:
Tonight we had the first clear sky after too many clouded nights (which isn't surprising, it's October after all!).
The Aurora started appearing just when Bz turned south. It took a while to develop to bright auroras, and in the mean time, it appeared quite "milky" to the naked eye (just like the Milky Way), but a picture revealed that it was almost only red! Rarely have I seen anything like this before.
Afterwards, we were treated to the usual swirls of green and even some nitrogen fringe.
And when the swirls calmed down, the aurora started displaying very distinguishable needles, with, again, some clear red on top.
Maybe Dr. Phillips can explain all the red... Slow solar wind, high (relatively) proton density?
PS: I had to check my white balance several times, and it's the same color temperature as on all my northern lights pictures :-)
