Clear skies, but the cold front is moving in with heavy winds and a “dancing” Sun, especially looking at limb.  The Sun is spotless for two days now, and we logged spotless day 895 since Solar High in Cycle 24.  I wonder when we will reach day 900 :-) . The  faculae and plages of the last Active Regions can still be seen in the closeups.
