7 Nobember 2009

Observing LocationTotL
Observational Period1830-2230 EST
The wind affected out ability to observe and I was very conscious or the pain in my hips and knee so this was an earlier night than it would have otherwise been. Mark and Hawiian George were there talking with us but both of them got cold and left just before we did. And it wasn’t even that cold -- just 50° F.

The weather forecast was for the wind to continually drop through the night but it didn’t happen. When I arrived it was pretty still but it started gusting shortly thereafter and when Peter arrived the gusts were strong enough they they were pushing his telescope around in the rocker box. As I result we only looked at Jupiter and that only when a passer-by passed by and asked what we were doing. The Central Park NOAA weather station up behind Belvedere Castle didn't record as much wind as we were experiencing on the ground at TotL.

TransparencyGood
There is some haze up there that is affecting transparency. The sky is a dull gray. ζ Cas (Mag 3.66) is hard to see. I don't see η Cyg (Mag. 3.89)at all but am seeing 31 Cyg (Mag. 3.79 and 32 Cyg (Mag. 3.98). δ And (Mag 3.27) is coming and going. And I can see &epsilon Aur (Mag 2.99v) and ζ Aur (Mag, 3.75) but not η Aur (Mag. 3.17), The Kids.

I could see the Equatorial Bands but not much more due to scope movement. ι Cap fit in the eyepiece with all of the moons.

CommentsA park maintenance worker pulled up his cart close to us and came over to see what we were doing. He had heard of Peter from Tom with whom he has observed some. Peter showed him Jupiter and the Doule Cluster. I don’t remember what it looked like tonight and don’t know if that is because I am so accustomed to seeing it or if I didn’t take a look.

Virtual Moon Atlas graphic
We could see the Moon rising through the thinning canopy of the trees to the east of the Central Park police precinct just before we left the park. As we got to the edge of the park Peter called my attention to the Moon shining yellow through a window in the trees. By the time we got down to Columbus Circle, which took a long while in a cab due to construction delays, I could see it above the Maine Memorial and it was no longer yellow.
