The west hemisphere becomes less active with AR11836 and AR11837 both turned to the far-side, leaving just several small prominences along the NW limb. |
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 SW is crossing the meridian and continues to develop, and the large dark filament has disappeared.
The huge filament to the east of AR11838 has diminished, but the S-shaped filament to the south is growing, and part of it is still outside the disc, producing several eruptive prominences.
The eruptive prominence that showed up on the SW limb erupts with jets shooting up high into the corona.
