AR11855 is is now close to 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.  Several flares appear today.
AR11854 and AR11859 are small but show some minor flares today.

AR11858 has turned to the backside, but some flaring appear today.

On the solar limb, the prominence on the E limb has changed a lot again since yesterday.
The jet-like prominence near the N limb is atill erupting.  Many more appear along the SE and SW limbs.
