MDM Observatory 1.3m Telescope Observer's Report for 2008 Jan 17

Observer(s): Denney & Grier
Institution(s): OSU

Instrument: CCDS

Worked for 12 hours (all night)
Conditions were Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Clear, Winds Calm
   Mid: Clear, Winds Calm
   End: Clear, Winds Calm

Observing Summary:

The weather was great tonight, and we were able to observe all night.

We had unresolved issues with CCDS from last night, but observed
anyway.  We're just missing a couple hundred columns of readout
from the chip, but the rest of the chip seems to be unaffected, so
we took observations anyway.  We were observing 3 grating settings
across optical wavelengths from ~3500-7000A, and hopefully our 
overlap regions are large enough that we'll really only suffer at 
red end.  We actually had to change one of our grating centers
because H_alpha was chopped off in one object.

Despite these difficulties, we observed all three grating settings
of PG1411 and Mrk110, and one grating setting of PG0026, plus 
standard stars.

We had some issues with the Ne lamp - details in trouble report.
