AR2776 has now turned to the far side of the Sun.  It came around the Eastern limb on the 14th of October when I captured my first images of it, and when it still was unnamed.  The Active Region has given us a pre-show of Cycle 25 activity, including some B, and C-class flares, as well as Ellerman bombs on October 17th.  A total of 19 B-class flares and 2 C-class flares could be observed.  AR2776 was not that big but  it covered an area of 100 millionths for one day on October 19,  and the region’s morphology was nice to follow, which is presented in the image below.  Please click on the thumbnail to see a larger image.
