18 September 2005

Observing
Location
Met Oval
I got out a little later than usual tonight and the sun could not be seen from PSC. Neither could it be seen from any of the benches around the fountain at Metropolitan Oval. I ended up having to stand on a traffic island on Unionport Road and count the spots while the sun was slipping behind a building. The ecliptic must be rising rapidly now.

TargetSunspots
ConstellationLeo
CategorySolar
Time1800 EDT
CommentsIt was difficult counting sunspots standing there with nothing to lean against and no tripod. Even with image stabilization turned on they were hard to make out.

[I was uncertain at the time of my observations where the equator was and which hemisphere the spots were in but called the one north and one south and looking at the satellite images after the fact I was correct.]

SW quadrant. This group is moving toward the limb and getting hard to see due to foreshortening
810
NE quadrant. This group has just moved onto the disk and is still foreshortened.

Atmospheric
Conditions
It was very pleasant with the temperature at 72° and the humidity low. There were no clouds and the sky looked clear, but the moon was making it hard to see things none the less. The air was very stable.
It would have been a good night to have done a NELM assessment while I was standing around waiting for the moon to rise above the trees, but I didn't do it.

CommentsSagittarius was moving through the gegenshine. I was able to locate all of the teapot naked-eye except for the handle on the top.

CategoryDeep Sky Object
Time18Sep05; 2130 EDT
CommentsI dropped onto it before I had even figured out where my binoculars were pointed.

TargetMoon
ConstellationPsc
CategoryLunar
Time18Sep05; 2200 EDT
CommentsThe limb looks rough from Strabo at around 12:30 down to La Perouse at around 3:30.
Mare Tranquilitatis, Mare Fecunditatis, Sinus Asperitatis, Mare Vaporum and Mare Nectarus are all a uniform gray and when combined look very circular. They give the impression of being a giant crater with the area around Isidorus, Capella, Gutenberg and Guclenius being a central peak.
There is not much relief showing anywhere on the disk.
The predominant features are the Marea, Plato and the rays.

CommentsCapella was still low on the horizon when I observed it and it was flashing like an emergency flasher.

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.
