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.
