The west hemisphere becomes less active with AR11836 on the limb to the north and AR11837 turned to the far-side. However, the huge prominence near AR11836 is still very active on the NW limb, and another eruptive prominence shows up on the W limb and should be from AR11837.
Meanwhile, the activites of the SE quandrant continue to develop. AR11838 shows many filaments and flares. The huge area of plages and flares to its south continues to develop, and the large dark filament has diminish a bit.
The huge filament to the east of AR11838 has all entered the solar disc. A S-shaped filament appears to the south, and part of it is still outside the disc, producing several eruptive prominences.
A group of prominences shows up on the SW limb, and seems to be very active.
