Clear skies with average seeing.  The Sun is spotless today for spotless day 16 in the current streak and spotless day 19 of the current rotation.  A small but distinct filament in the North near the meridian, and some nice proms at the NE and the Eastern limb.  Today full disk images and a close up of the filament and the NE prom.
