MDM Observatory 2.4m Telescope Observing Report for 2013 Apr 13

Observer(s): Dan Gifford
Institution(s): University of Michigan

Instrument: OSMOS

Worked for 9 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

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

Observing Summary:

No major issues, however for multiple masks the dispersed light through the slits 
(comp, flat, and science images) all showed a slight bending toward the edges of the 
field. Now that I notice this, I also see much slighter versions of this deformity in 
the data taken on previous nights. Have other observers noticed this with OSMOS?
The wind began picking up again tonight, but never a threat of closing. Excellent 
seeing despite the wind!
