Clear skies again with strong wind gusts.  A spotless Sun today for spotless day 205.  The old region is still visible as a plage and it looks like something is forming at the Eastern edge of the Sun. A small filament in the North and a small prom at the NE limb are visible.  In visible light, the sun looked empty.
