Details:
Fairly good weather conditions this morning, but for brief time, allowing me only these short Sun timelapses in the red chromosphere (Hydrogen alpha filter). The whole face timelapse shows varied simultaneous activity (eruptions, flares) in various Active Regions, a hedge prominence (spectacular in eyepiece) and a pair of unsettled filaments. The hedge prom was already visible yesterday but today rotated better into view. It is part of a long filament connected to AR4136, which has delta classifier. Both the region and the filaprom are fairly active these days. However, the most active region in latest days has been AR4140, which produced various eruptions and some M flares, including two this morning. I missed these flares for cloudy/rainy weather. When I captured these images the activity was at C2 level.
