MDM Observatory 2.4m Telescope Observing Report for 2012 Feb 19

Observer(s): Marcel Agueros & Emily Bowsher
Institution(s): Columbia

Instrument: Modspec + Nellie

Worked for 4 hours (last half of the night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   High Humidity all night.
   Beg: Clear, Winds Calm
   Mid: Clear, Winds Calm
   End: Clear, Winds Calm

Observing Summary:

High humidity and threatening clouds kept us closed until 2 AM
or so. Our data thereafter were so-so at best; there seemed to
be a very high background that got worse as the night went on. 
We closed a bit early as a result. The humidity did drop to 
60% or so, but rose steadily back above 80% and is now around
75%. Unfortunate.
