2015 Aug 3-9 observation of AR12396

AR12396 turns to the front side on about August 02, but not observed.
These images are taken from August 3 to 9 (except that no observation was done on August 4).
Lots of flares show up, so are the many changing fibrils/filaments.

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.
