AR12422 is now midway between the meridian and the SE limb.
Its full extend is in view and many flares and filaments show up.
At about 10:34 a violent eruption shows up from the following (east) spot and gives a spectacular "spray" like dark filament that lasts until about 11:11.  Another eruption follows, this time from the leading spot and the resulting filament shows until about 11:50.

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.
