Clear skies today.  AR2821 has turned around the edge, but we still see AR2818 in all wave lengths and AR2820 shows as a plage in Ha and CaK.  In addition to some very small proms, a string of filaments can be observed in Ha in the SE, as well as a small plage near the Northern Central Meridian in CaK
