You would be correct with that assessment Joe. We've had a lot of clouds in S.W. Missouri of late. Also, I am in wood cutting season. Getting fuel for heating the home and water takes priority on the weekends anymore. Should be done with that in 2 weeks though. I look forward to imaging the sun again, it's been a while...almost 2 months.

Hi Federico, this from a paper written by S. Ramsden and A. Hart. I hope it answers your question:

Ca II K is the lower chromosphere, 500-1500 Km above the photosphere.
the filter is centered at 393.4nm with a bandwidth of 0.22nm. This gives a range of 393.29nm-393.51nm. In the literature the Ca II K line is split into 3 regions, the K1, K2, and K3. Each region shows a specific area of the chromosphere and with the K1 region being 393.32nm to the K3 region being at 393.37nm (where prominences can be seen) the bandwidth clearly covers the whole of this region of the chromosphere giving a general mix of heights visible in the chromosphere in Ca II K filters. The K1 or K2 region (500-1000 km) is lower than the Ha; core region (1500 km) above the photosphere, but the K3 region is around 1800 km in height.

Clear skies to you and Pat.
