Group 940 is gone for me. If it is still there it is too close to the limb for me to pick it up. Group 941 appears small in this binocular, but I expected that and since it has been a solitary spot with a small penumbra, and the only spot I expected to are, I didn't think there was a lot to be gained in carrying the heavier binocular.

I can't tell much about the spot other than that it is there.

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.
