The Dutch Observatory

Clear skies for the observing session on 9-4-2021 with great seeing.  I had a visitor this morning and we did observe together. Because of this I am a day late with my submissions.  But, here they are.  The Sun was real busy.  AR2863 in the southern hemisphere increased to a nice 160 millionths. The region in the Northern hemisphere was also named as AR2864 and the spot that emerged not far from it as AR2865.  A new area with a number of spots showed near the SE limb has been named in the meantime as AR2866.  Full disk images today with closeups of AR2863, AR2864 and 65, an AR2866 in the three wavelengths.

Clear skies during the observing session.  Wow, the Sun is really busy today.  AR2863 still shows nicely, although it has decayed a lot to 90 millionths. AR2864 and 2465 show nicely next to each other in the Northern hemisphere, although I could not make out spots in AR2865. AR2866, AR2867, and AR2868 show in the Southern hemisphere.  AR2866 and 68 in the SE quadrant and AR2867 at the limb in the SW quadrant and only was visible in the CaK observation and close up.
