On Monday, May 6, an X4.5 class flare was seen in the Sun. I was photographing The Sun at the observatory of Tampereen Ursa just then. Cloudiness disturbed the observations somewhat, but in the end I was able to create a video just when the flare was at its strongest. I stacked this image from this video. This was the first time for me that I could observe (live) such a powerful flare. The smaller ones are stuck in the camera's memory.
