MDM Observatory 1.3m Telescope Observing Report for 2009 Jun 27

Observer(s): John Tobin
Institution(s): Michigan

Instrument: 4K

Worked for 4.0 hours (part of the night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

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

Observing Summary:

No storms tonight but the sky was quite cloudy until about 10pm, 
by ~11:30pm it was clear enough to observe. I managed to get some
decent data for the Trifid nebula, though there was still 
interrmittent cloud cover during the observations and around 1:30am
it got cloudy again. I waited for awhile but closed up at 2:30am.

The guider has functioned quite well during my run, I have not
experienced the N-S jumping that has been frequently reported.
My guider parameters are integration time 1.0 seconds, ra and dec
guide rates of 4.0 (default is 2.0). Though, I can't say that
my limited amount of open time has fully experience all
the possible triggers of the problem. I have spent most of my 
observing time pointed south at -23 degrees declination with low
hour angles, always less than +/-2 hrs.
