#Sunspots! They're back!
This is my view of Active Region #AR2778 on the #Sun, yesterday 2020-10-28.
Fun fact: Sunspots are temporary, dark, and *cold*! (in relative terms)
Fun fact: There are MORE today!

The input data, started from the actual monochrome capture (using a green photographic filter), like this.

Just for fun, here is a close-cropped view of this #sunspot group. It's continuously changing, as they do, but it's obvious from hour to hour.
Fun on the #Sun!
