The day started with clear skies, but clouds came in and limited my time.  So today only 540nm images.  Since AR2835 is nicely positioned across the meridian, solar granules are nicely visible in this image and one can see that AR2837 is double bridged.  AR2835 has increased to cover 370 millionths, but has not shown any significant flaring.  Neither has AR2836, which produced a C-class flare on the 27th.  A new region has been named AR2837 in the NE quadrant.  Today’s images show the full sun and close ups of AR2835, 36, and AR2837.
