AR12403 has become more and more complex.
Flares and filaments are produced non-stop.
The regions around the following-spot produce lots of flares.  The flare to the west of the following spot erupts at around 10:38 when I plan to stop observing and has the electricity power of the oven disconnected.  I have to reconnect the power after seeing the eruption.

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.
