MDM Observatory 1.3m Telescope Observing Report for 2009 Sep 02

Observer(s): Terndrup, Parks
Institution(s): OSU

Instrument: 4k

Worked for 8 hours (off and on through the night)
Conditions were Mixed most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Clouds all night.
   Beg: Seeing 1.5 arcsec, Patchy Clouds, Winds Calm
   Mid: Seeing 1.8 arcsec, Overcast, Winds Calm
   End: Seeing 1.2 arcsec, Patchy Clouds, Winds Calm

Observing Summary:

The entire night was hit or miss with clouds.  When patches of 
clear sky were open for the clusters we were interested in, the
images were generally good. Seeing hovered between 1.5 and about
2 arcseconds for the majority of the night, but got as low as 1.2
near the end of the night.  The guiding worked very well when 
clouds allowed it to have enough counts.  The only minor problem 
came during the very last task of the night.  After filling the
dewar, I attempted to remove the hose too early and split the
tubing where it connects with the nitrogen tank.  I cut the 
split part of the tubing off (after detaching from the tank) and
reattached the remainder, but if it is too short, I can replace 
it with a longer tube tomorrow if a longer tube is available 
somewhere.  Sorry!
