The active region on the E limb that gave show of many prominences finally turns to the front side and is numbered AR11836. There are still many eruptive prominences associated with this AR and it may become interesting in the coming days.
The centre of activity seems to be to the NE of the sunspot, at the junction of 2 filaments, where a flare shows up at 12:01, but disappears by 12:11.

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
