Details:
For several days over my city, Rafaela, in the province of Santa Fe, Argentina, the sky is completely cloudy and we have rains. This Thursday around 11 a.m. (local time) the clouds moved a bit and I had time to set up the H-alpha telescope and capture a few images of the AR2776 sunspot and a huge prominence that appears in the upper left. A filament is also visible in the sun's northeastern limb and may be the possible origin of the flare detected this Saturday 24. Shortly afterwards it became completely cloudy again.
The photo was taken at 2:07 p.m.(UT) from my backyard.
To capture this image I used a 90mm SolarMax II Coronado single stack telescope and ZWO ASI 183 MM camera.
I made two videos of 730 frames each, one for the disc and one for the prominences and stack 21% of them.
To highlight the details of the disc I inverted the image in Photoshop.
