Finally I got time to finish my report on Wednesday’s imaging session.  Solar Activity remained Very Low with no flares in the previous two days.  AR2664 increased a little to 100 millionths but the spot number decreased by 2 to 7. Some small filaments were visible near the NE and the NW limbs, as well as a small prominence on the Western limb. Otherwise not much activity.
