Most active regions are near the W limb. AR11834 and AR11836 are in the northern hemisphere, with AR11834 right on the limb. The huge filament is now half on disc and half "floating" above the limb, producing some interesting eruptiions.
AR11835 has all disappeared to the far side, while AR11837 is close to the limb.
AR11838 has turned to the front side, just to the south of the equator. Furhter to the south is a huge area of plages and flares, and a large dark filament.
On the solar limb, several prominences are present. Apart from the eruptive one that is associated with AR11834, the "floating" one on the W limb is associated with AR11838. The prominences on the SE limb is also associated with the "active"regions cloeby.
