AR11855 is is now approaching the west limb, but its activity has subsided.
Lots of plages and fine filaments are seen in the southern hemisphere, along the strip between AR11855 and AR11857.  

AR11856 and AR11857 continue to develop in the last 24 hours into large and very active regions.  
AR11854 has subsided into a small ring of plages.  The samll AR to its south, and west of AR11855 is now named AR11859.  It shows some minor flares today.

AR11858 is right on the NW limb and not much activity is seen.

On the solar limb, the prominence on the E limb has changed a lot since yesterday and may be very interesting in the coming days when more of this group turns to the front.
A jet-like prominence near the N limb is erupting.
