This afternoon the temperature went up till 29,5°C. Clear sky and thus time to take some pictures of the sun using PST40. A total of 3 prominences could be observed.

22° Circular Solar Halo @ Averbode
WOW! First time ever I'm witnessing a full halo around the sun. Before, the halo was not entirely full but this morning the 22° halo was circular. A fantastic phenomen easily seen with the naked eye but difficult to photograph.
