The west hemisphere remains active with AR11836 to the north and AR11837 on the SW limb.
Meanwhile, the SE quandrant appears to be full of activities, with AR11838 moving inside the solar disc and shows many filaments and flares. The huge area of plages and flares to its south continues to develop, and the large dark filament is persistent. A huge filament is making its appearance to the east of AR11838, and may be connected to the eruptive prominence on the W limb.
On the solar limb, several prominences are present. The huge filament-turned prominence that is associated to AR118334 is now fully edge-on on the NW limb, and is producing lots of eruptive features. the "floating" one on the W limb is associated with AR11838. The prominences on the SE limb is also associated with the "active"regions closeby.
