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.
