AR11856 and AR11857 are now in the western hemisphere. The former, in the north, is very active with flares and surging filaments, while the latter, the south counterpart, is relatively quiet.|
Close to the SW limb are the pair of AR11862 and AR11866. Both start to become very active in the past 2 days. AR11862 produce mainly flares and AR11866 shows surging filaments. A small active patch to their NW is also developing.
The small active group that produced many eruptive prominences on the SE limb a few days ago has developed into very large active regions and are named AR11861(the dominating leading group), AR11864 and AR11865. Lots of activites are visible and AR11861 is producing flares nearly non-stop. Many active dark filaments are also showing. These AR's are expected to develop further and may become spectacular in the coming days.
2 small AR11860 and AR11863 are crossing the meridian in the south. They are associated with several filaments.
On the solar limb, the prominence on the W limb may be associated with the active regions AR11862 and AR11866. These prominence may become interesting when the AR's go edge-on.
