AR11850 which dominated the solar surface a week ago, is now nearly edge-on in the NW, and is associated with the eruption on the NW limb.
It is now AR11855 that dominates the solar surface.  This AR is closing to the meridian in the south and is avery active.  Flares show up nearly continuously, so are the small dark spikes that come as a result of fast shooting jets.
An active but not named regions has turn to the front side near the SE limb.  This group comes, apart from the patches of bright plages, a thick dark filament,

The small AR11854 is close to the solar equator in the north.  Some bright patches of plages are visible together with some filament.
Just to the north of this area come several jets on the limb, indicating some active area just round the corner.

2 long strip of filaments running in the E-W direction extend almost 2/3 of the solar disc.  These fialments are part of a long strip of activity along mid-latitude in the north.

On the solar limb, many prominences show up and several are ruptive.
