The Aurora season has arrived

Finally the dark nights are back and it's a joy to once again be able to enjoy the night sky. The last few nights we have had some really nice aurora displays. The sky is still a bit to bright but for every day its rapidly getting darker.

This photo was taken last night and shows a beautiful aurora arc with some nice curtains to the left. There's also some purple colors in there but they aren't that prominent when the sky is still pretty blue and not black.

I hope we'll get another great aurora season but the number of aurora displays are expected to drop. It's the Sun's activity (sunspots, flares and coronal mass ejections) that causes aurora.

The Sun's activity has a periodic solar cycle of nearly 11 years and in 2014 we passed the latest solar maximum so the solar activity and therefore aurora is expected to drop over the years to come.
