I entered The Great Lawn from the Delacort Theater path and walked counterclockwise around the Lawn to try to see if I could see any of the planets. Venus was at about 7° elevation at that time and I think we have previously determined that out local horizon is around 5° so at least Venus should have been visible. I can't tell if there were clouds in the way or if it was behind a building or tree but it doesn't much matter as no planets were visible.

CommentsA large bright area of sky with no definition. Not a dust bunny. We used a nebula filter and that increased the contrast greatly. With the filter it looks more like a dust bunny. It appears to me to be elongated diagonally 11:00 to 5:00 with a waist. At times it looks like it is C shaped or a backwards J, like a fetus. There appear to be threads coming off of it in numerous places that remind me of a diatom.

CommentsI looked at Jupiter in my binocular mounted on the monopod. I saw one moon ahead of the planet and one trailing and thought I might have seen a third moon above the plane and close to the planet. Peter confirmed the two in-plane moons but did not see the third. It turns out the moon closest to the planet was actually Io and Europe either gong into or coming out of an occultation.

18 July 2010

I was supposed to have backed out some past observing reports this weekend. Unfortunately my laptop died during the week and we think it is beyond resuscitation. It was an old machine. I have a new, to me anyway, MacBook on order but it may not arrive until the end of the month. Then it is going to take a while to set it up. Some of my astronomy software is PC only so I am going to have to run a virtual machine and install Windows and the PC programs on it. I had been doing nightly backups of most of my data so I probably haven't lost much. But the back out I had started last weekend was saved to the desktop and that doesn't get backed up. And each time I entered the data into the blog template I deleted it from the Palm log so half of that nights Observations may have been lost forever.
