My observation in the morning was mostly focused on the huge prominence on the west limb. However, there were lots of changes recorded in these AR's.

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
