MDM Observatory 2.4m Telescope Observing Report for 2011 Mar 30

Observer(s): M. Dietrich
Institution(s): OSU

Instrument: OSMOS

Worked for 9 hours (all night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Cirrus, Winds Calm
   Mid: Seeing 1.2 arcsec, Patchy Clouds, Winds Calm
   End: Cirrus, Winds Calm

Observing Summary:

During the first half of the night strong cirrus lowered the 
transparency and the conditions got worse toward the middle of the
night with some cloud cover. For a while only stars brighter than
2 to 3 mag were visible and the guide stars were lost. At the end
of the night the transparency improved. In spite of these 
conditions spectra of 5 BALQSOs were recorded. In the case of the
fainter ones the spectra show a very low count rate (~30cts max.).
