Clear skies with good seeing conditions. Today is a special day since it is the 750th spotless day on the Sun since solar max as reported by SWPC. In fact, the sun is real quiet today. The only item I could make out was this very small prom at the SW limb visible in the full disk Ha image. For the rest it was a blank disk, even in CaK.
