Clear skies this morning.  AR2806 has decayed to a plage just before it turns to the far-side of the Sun, and AR2807 has reemerged but it is barely visible.  A new area has rotated in view and is visible near the NE limb.  The area was named AR2808 this morning and the Wilson effect is very nicely visible in the 540nm close up image.  Full disk images today as well as close ups of the regions of interest.
