MDM Observatory 2.4m Telescope Observing Report for 2015 Feb 21

Observer(s): Stephanie Douglas, Jose Zorrilla
Institution(s): Columbia University

Instrument: ModSpec/Echelle

Worked for 3 hours (off and on through the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds all night.
   Beg: Cirrus, Winds Moderate
   Mid: Patchy Clouds, Winds Moderate
   End: Patchy Clouds, Winds Moderate

Observing Summary:

We opened at sunset and were on sky at twilight, but we only got 
one object in before high clouds blocked everything. The clouds 
thinned out, so we opened again around UT~4 and got another hour 
on sky. Then patchy clouds rolled in so we closed.  A big hole 
in the clouds opened overhead around UT~8:30, so we opened again 
and got another hour and a half of data. When heavy cloud cover 
started coming over from the north, we closed for the rest of 
the night. The seeing was pretty bad most of the night.
