MDM Observatory 2.4m Telescope Observing Report for 2011 Sep 09

Observer(s): Paul Martini, Joe Antognini
Institution(s): OSU

Instrument: OSMOS (Red detector)

Worked for 5 hours (last half of the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds from 19:00 until 23:30.
   Beg: Overcast, Winds Light & Variable, High humidity
   Mid: Seeing 1.3 arcsec, Patchy Clouds, Winds Light & Variable
   End: Seeing 1.3 arcsec, Clear, Winds Moderate

Observing Summary:

The first half of the night was cloudy.  After a few hours the clouds cleared up, but we had to remain closed due to high humidity.  By 7 UTC we could open up.  The seeing was not great, but we didn't have any problems with clouds for the rest of the night.

We tested the red-sensitive detector on a spectrophotometric star and a few high-z quasars.  Its sensitivity seemed to be anomalously low, so we did not have much luck detecting the high-z quasars.
