Scattered clouds this morning, but enough room for a full imaging session.  The Sun’s activity has been Very Low since the last C-1.7 class flare on June 19th, and has not shown any Sunspots since June 23rd.  So we focus on other features, such as the beautiful filaments that are crossing the solar disk in the last few days.  Today three full disk images as well as close ups of the filaments in Ha and the region that produces them in CaK.
