Not a perfect day but the Sun shone for a while.
The new active region 11054 in the north east sector has developed into a "white light" spot group with two large spots with clearly differentiated penumbrae & umbrae. There are also pores associated with active region 11055 south of the disc centre.

In Ha, several prominence groups are visible, also an elongated filament north of the disk centre and a broad one near the west limb.
