MDM Observatory 1.3m Telescope Observer's Report for 2006 Feb 11

Observer(s): Denney and Bentz
Institution(s): OSU

Instrument: CCDS

Worked for 11 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 2 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 4 arcsec, Clear, Winds Moderate
   End: Seeing 4 arcsec, Clear, Winds Moderate

Observing Summary:

We had a fairly quiet evening.  The seeing deteriorated throughout
the night, but we were still getting a good amount of light down
the slit.  We obtained spectra of Akn120, NGC4051, and IC4329A 
at three grating positions.  We also managed to get 15 minutes at 
each setting for SN2006X, this time with the correct object in the
slit.  Unfortunately, the seeing was pretty bad while observing
the supernova, so the spectra are lower S/N than they could have
been.

We had one glitch in Prospero tonight.  Details follow:

pr> center 5450
    setting central wavelength ...
E> DONE: GratTilt=51832
    Error: Requested Operation Timed Out
    CENTER command aborted with errors
    Usage: CENTER n
    Execution error in Prospero command
    Command: center 5450

After receiving these messages, I then issued the same command
again, and that time the grating recentered.
