Finally clear skies, but the seeing conditions were marginal. A small area about 8 degrees N in the NE quadrant, which according to SDO imagery started forming yesterday afternoon, is still there but was not named by SWPC, so they called for a spotless day. The area seems to decay. The very bad seeing during the time of my capture of the WL version of this area made for a bad image, whereas the Ha and CaK images were better. In addition we could observe two faint proms on the SE and SW limbs as well as a filament in the higher regions near the NW limb.
