Following yesterday’s cloudy skies, today was clear with good seeing. Another spotless day, making it spotless day 463 since Solar maximum and increasing the current spotless streak to 24 days and counting….  So far we had two longer streaks which ended on 11/12/2018 with 25 days, and 3/5/2019 with 33 days, but still short of the 52 days during the transition from Cycle 23 to Cycle 24.  However, we see a nice filament curving at the western limb and some nice proms.
