Todays image through low clouds, interesting to see AR11579 is showing a good example of the Wilson effect.
This is where the spots flatten as they reach the edge of the disc, this then proved that they were actually on the surface of the Sun and not as some thought were objects or moons orbiting.
Spot count 55
