Finally some clear skies again after a streak of cloudy days. Seeing was below average.  Today on spotless day 310 we see a few small pores near the Western limb, which show as plages in Ha and CaK, as well as few faint proms at the SE and SW limb.  Other than that the Sun is uneventful today.  It has been 8 days since we had the last flare which was a B2.3.
