Solar activity

 The solar activity is definitely picking up. The past few days has been clear, so I have been able to make some timelapses of a group of sunspots. The first day wasn't very active, but today, there was a lot more flares and prominences flashing. I also made a mosaic of the whole surface of the Sun. This was made up of 9 images.
