AR11855 is is now west of the meridian and is still dominating the solar surface.  There are still lots of flares popping up in this group.
The active but not named regions has changed a lot since yesterday. It has dispersed into a large area of plages but no flare.  The thick filament has also disintegrated.
The 2 very active groups near the SE limb have turned to the front and are named AR11856 and AR11857 respectively.  Lots of activities are visible here, with many surging filaments.

The small AR11854 is close to the solar equator in the north.  Some bright patches of plages are visible together with some filament.

A small but very active AR shows up near the NW limb.  Flares erupt nearly continuously during the observation session this morning.

On the solar limb, several prominences show up.  The one on the SE limb is eruptive.
