MDM Observatory 2.4m Telescope Observer's Report for 2008 Feb 24

Observer(s): John Thorstensen
Institution(s): Dartmouth (for Columbia)

Instrument: Echelle CCD direct + 4 in FW

Worked for 11.5 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1 arcsec, Cirrus, Winds Moderate
   Mid: Seeing 1.5 arcsec, Cirrus, Winds Moderate
   End: Seeing 1.3 arcsec, Cirrus, Winds High

Observing Summary:

There was always some cirrus around, but it only got heavy, once
again, after midnight.  Scattered moonlight (gibbous) was 
problematic, and attenuation not trivial either.  Managed to 
work through it except for one particularly heavy half-hour
stretch.  Winds picked up toward morning, but never approached
the limit.  Got a pretty good haul of parallax data, but I could
sure use some good conditions in the morning -- parallax 
displacements are greatest at morning and evening twilight.

No equipment problems.
