I got out and was having trouble locating the sun in the telescope since it was very high in the sky. I was noticing flashes of light as I moved the scope around and took the filter off to reexamine it and found two holes in it that I had missed on my initial check. And these were big holes. It looks like they got worn in the filter while it was being transported to and from Queens last weekend. They appear to be right where the bars on the protective cover end and I surmise that pressure on them wore through the film. I will have to patch them with aluminum tale. I had to run home and get the binocular to make the observation.

A dark central spot with penumbra and something preceeding it and beneath it that I am interpreting as smaller spots.

We were looking at the Moon when the sky went south. It didn’t take long. Stan, a photographer/dog owner stopped by and said he was surprised to find us still there and mentioned the sprinklers then Peter said something about feeling a drop of rain and it wasn’t long before we were scrambling to get all of our equipment packed away.

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.
