Clear skies with a few clouds streaking through.  Another Spotless day.  Today the Sun is as quiet as I have not seen it often.  No proms, or filaments, only a very small area showing a little activity (plage)  in Ha and CaK.  Could not detect a faculae in 540nm.  It looks like some spiculas or strings of plasma are showing in a half circle extending from the southern part of the area, circling West and North.  Clouds moved through the Eastern portion of my CaK image.  Today full disk images, as well as a close up of the mentioned area.
