Clear skies before the clouds came in.  The seeing was average.  We are at spotless day 296.  It has been a real long time since I’ve seen the Sun as quiet as it is today.  No small plages in CaK and only a very small filament at the NW and SE limb, while we could observe three very small prominences at the E, SE and NW limbs. Full disk images in the three wavelengths as well as close ups of the mentioned regions.
