AR11855 is is now mid way between the meridian and the west limb. There are still lots of flares popping up in this group.
The active but not named regions near the SE limb has changed a lot since yesterday. It has dispersed into a large area of plages and filaments but no flare.
AR11856 and AR11857 are developing into large and very active regions. Lots of flaring activities and surging filaments are observed. These two will dominate the solar disc in the coming days.
The small AR11854 is close to the solar equator in the north. Some bright patches of plages are visible together with some filament.
The small but very active AR near the NW limb is now named AR11858. Flares activities have subsided a bit since the day before.
On the solar limb, several prominences show up. The one on the E limb is highly eruptive and may be very interesting in the coming days when this group turns to the front..
