Details:
I read Anton Špenko's report about the appearance of a faint purple aurora last night. I also took some pictures in the NE direction at the same time, looking for some morning NLC, with a Canon 50D and a 28mm. lens hanging... 5 meters high on a telephone pole in my garden (amateur astronomy madness, but unfortunately from home I have little horizon and I have to recover it somehow...). I added 10 shots from 3:00 to 3:20 local time, to increase the weak signal and reduce the noise, and by "squeezing" the obtained file a faint purple area appeared above the horizon, which doesn't seem like the usual color to me yellow-orange light pollution. The sky area is the same, magnified to a 50mm equivalent focal length.
