Clear skies this morning with average seeing.  The region I imaged in the Southern hemisphere in CaK on the 10th, was named AR2809 yesterday morning, but it was short lived as it decayed already to a plage.  AR2808 decayed also a bit in the leading spot, so for most solar activity is Very Low.  Today full disk images and close ups in the three wavelengths.
