Today, observation starts at 8:15 am and I am awarded with superb seeing.
The solar surface is dominated by the 2 very active regions A11967 and AR11968.
Meanwhile, the huge prominence on the SW limb is still going strong after 3 days.

Telescope: AP Starfire EDT 155 mm f/9.
stopped to 50 mm for disc images, with 4X telecentric lens (f/36) for closeups
filter: Solar Spectrum SO1.5/0.3A with CERF prefilter
Camera: Imperx 4M15
North is up, and east to the left
