It looks like the components of this group are shrinking. The middle spots are much less distinct but I think there are still two there. The trailing spot is smaller and I do not detect any penumbra around it. The leading spot remains remains the largest and still has a penumbra but it is not as impressive as it was yesterday.

This group is a small pair of spots about half way between the midline and the limb. I saw the leading spot first and believe it to be larger although they are small enough that it is hard to tell. I don’t see penumbra associated with either of the spots.

Disclaimer
This is my personal record of my astronomical observations. It was written for my personal reference. The only reason it is in a blog is that a blog is a very convenient way to get the records formatted more or less uniformly and they will, hopefully, have greater longevity at Google where the servers are backed up than on my hard drive which never gets backed up. I occasionally include copyrighted material in my posts. I do this to make it convenient for me to access things I think I might want to refer to again. I think of this like making a photocopy of something I read that I put in a file where I can find it when I want it. As I understand copyright law, as explained in the DVD series Copyright Compliance by Chip Taylor Communications, this use is allowed under the Fair Use doctrine since I am not making any money on this blog, I don’t publicize the blog, and only occasionally post small excerpts of copyrighted works.
