The active groups of AR11861, AR11864, AR11865 and AR11870 in the SW are dominating the solar disc.  AR11861 and AR11865 are still showing many flares. A long twisting filament runs from the E of AR11861 to AR11865.
AR11860 is right on the W limb and is close to a group of active prominence.

AR11867 is close to the NW limb and is producing some surging filaments and flares.

AR11872 has just turn to the front near the SE limb.  It is following a group of active filaments and prominences.

In the NE area, the trio AR11868, AR11869 and AR11971 occupy large arena with many surging filaments.  Another small AR seems to be forming right on the E limb, just south of a large prominence.

Many prominences are visible on the solar limb.  The one on the E limb is large but low-lying.  The ones on the SE and W limb are eruptive.  The pair on the NW limb are structurally in great contrast.  Both are eruptive.
