AR12414 is very close to the west limb but the 2 large spots are seemingly connected by a "S" shaped filament and flares.
Seeing is not good.

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.
