Sun in CaK / White Light With Explore Scientific AR152 Refractor + Lunt CaK filter or Baader Wedge Uploaded 3/30/17 Daily Report For Thursday March 30, 2017
 After weeks of a blank solar disk, the sun has produced a few fine sunspot groups for examination. Seeing this month has been some of the worst I have ever seen in Arizona, and today was no exception. Occasionally, I was able to see hints of granulation at 5x, so the seeing I rated at 1.5/5 for today. I have two sets here, the first in white light and the second CaK in near UV wavelengths.

Lets start with prime focus in white light with the AR152 stopped to 4 inches aperture:

The first of two groups at 5x at about 5 meters focal length:

Second group is less exciting:

However in calcium light both groups are far more interesting!
