The Sun in Ca II K 14102020

I started today's imaging session in Ha, dodging clouds and murky skies in my first attempt to double stack.... enough said about that.
However, I have included an image of a quiet Sun in Calcium light featuring AR12775 and AR12774 with Earth added in for comparisons.
The little blip on the eastern horizon may be a new AR rotating into view.
