Here are photos of sunspot AR2192 from today and yesterday. I wanted to see it it changed much since yesterday. I think not. Most of the difference appears to result from our changing angle of view as the rotating Sun brings the sunspot to the center.
I use this blog as a companion to my website www.brightstarstemeculavalley.org, where I call attention to local light pollution and share my enthusiasm for science and astronomy. I'm also a contributor to www.SkepticalScience.com.
