Visibility IV / V
A reasonably impressive protuberance photographed from the Sun on June 28, 2020 at 9:36. The imaging tube is the familiar TMB 152/1200 APO lens tube combined with Daystar Quark Chromosphere Combo + Baader D-ERF filters and a Televue 4x PowerMate teleconverter. The occurrence of protuberances varies from day to day, so usually there is always something to describe in that Ha area. The picture can also be found on my website .
I added to the observation a raw image of the outbreak of a group of sunspots seen at the same time, which then neither became a more permanent group of spots on the surface of the Sun. (I haven't dealt with that as a final image.) There was more detailed information about that comma company on the SpaceWeather page at the time.
