August 8, 2017: More disks in Ca-K and WL

Post by michael.h.f.wilkinson »

I had beautiful clear skies in Fishers, Indiana yesterday morning, so got out the 80mm and shot a few more disks. Not much is going on in white light, just AR 2670 continuing its progress across the disk, but Ca-K does show some proms, especially in the part inverted shots, and more plage around the AR.

Best seen at full resolution.
I really hope some new ARs emerge before the eclipse, as the sun's disk might be quite bare come August 21, with this AR probably neatly facing directly away from us earthlings
