The clouds have finally disappeared for my sessions.  Today we see a spotless Sun again.  But as I always say, there is something interesting  happening.  We see some very nice C25 polarized plages in Ha and CaK and in one of them, near the center of the Sun,  we see two small pores in the continuum image.  The one in the South shows a very nice filament stretching from one side to the other in Ha.  The old AR2771 shows now as a plage.  Today full disk images as well as close ups in the three wavelengths.
