Clear skies but windy, and what was worse, a 130mph jet stream above causing bad seeing.  A spotless Sun again today (day 56). Full disk images showing some nice filaments in Ha and some plages in CaK.  I tried to image the faint and small proms at the NW limb, but the seeing conditions would not let me get the contrast I wanted.
