As AR11856 and AR11857 are close the W limb their activities are subsiding, although AR11856 is still producing some flares today.

AR11862 and AR11866 are on the W limb today, several jet-like show up together with minor eruptions.

AR11861 is producing flares nearly non-stop while AR11864 is relatively quiet.  AR11865 is also producing a few flares.  These AR's are expected to develop further while they are crossing the meridian, and may become spectacular in the coming days.  
A major eruption takes place around 12:09 but this flare subsides fairly quickly.  Look for major eruption in the coming days.

The small AR11863  and AR11867 are active.  They are associated with several flares and filaments.

The dark filaments on the NW limb are mostly out of the disc and are producing some eruptive prominences,  The promineces are spectacular.
