As CR2236 is coming to an end tomorrow, so is the visibility of AR2778 and 79. These two regions are pretty close to the Western edge and tomorrow they might not be visible any more. Clear skies here again today but the seeing conditions are just terrible. Despite this I captured the regions in all three wave lengths as well as the full disk images.

Well, the recent storms have impacted my observing quite a bit, but today was clear, although the seeing conditions were far from good. My first images from the two new regions AR2778 and AR2779. AR2778 has really taken off, with an area covering today of 300 millionths!! However. both areas will soon turn to the far side. Today full disk images and close ups of the mentioned areas.

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.

Did not expect it but we did have clear skies AR2766 remains stable and unchanged with 60 millionths and one spot. The unnamed area in the NE, now shows near the central median in the Northern hemisphere but remains unnamed so far. In addition a prom was visible at the Eastern limb. Today full disk images as well as close ups of the two regions and the prom.

Clear Skies today with good seeing. Today, AR2776 moves further to the Western limb and a plage which was visible yesterday near the NE limb is very visible in Ha and CaK. I could not make out a spot in 540nm. AR2776 covers 60 millionths and still shows one spot. Today full disk images and close ups of the two regions mentioned.

A very few openings between clouds, so only full disk images today. AR2776 is steadily tracking towards the Western limb as it slowly decays. Yesterday to 80, and today to 60 millionths, and it’s got one sunspot left.

Clear skies today. The plage I mentioned yesterday near the SW limb developed a spot which was named AR2777, covering 10 millionths. However this morning it had turned to the far side, so we only see AR2776. AR2776 has grown a little more to 100 millionths. The light bridge which was visible in yesterday’s images has mostly disappeared. We’ll have to wait and see what happens next to AR2776.

Clear skies for another observation session. AR2776 has grown a little to 80 millionths, and has shown some B-class flaring. In addition, a plage could be observed near the SW limb. The NE and SE limbs showed a few proms, but some thin clouds made it hard to get a good focused image. Today full disk images and close ups of the Proms and AR2776.

Clear skies with better seeing than yesterday. AR2776 has doubled in size to 60 millionths, but still supports 4 spots. Today again full disk images and close ups of AR2776 in the three wavelengths.

Just time enough between the clouds to image the Sun. The area that emerged on the 14th has been named as AR2776 and measures 30 millionths with 4 spots. The plage from AR2775 is ready to turn to the far side but still showed nice for a close up in Ha. Today full disk images and close ups in the three wavelengths.
