MDM Observatory 2.4m Telescope Observer's Report for 2002 Feb 12

Observer(s): Pinkney
Institution(s): Michigan

Instrument: ModSpec+Echelle

Worked for 10 hours (most of the night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 0.8 arcsec, Cirrus, Winds Calm
   Mid: Seeing 0.7 arcsec, Cirrus, Winds Calm
   End: Seeing 0.8 arcsec, Cirrus, Winds Calm

Observing Summary:

Bob and I focussed the spectrograph because the Wilbur
CCD had to be replaced by Echelle.  Although the comp
line widths looked good, the first focus frame of the
night revealed a varying width of the spectrum.   So
the collimator had to be adjusted closer to the nominal
value and the rest of the plate values had to be reset.
I ended up with a better spectral focus, as well as 
spatial focus, but this took up a few hours after sunset.
