MDM Observatory 2.4m Telescope Observing Report for 2015 Apr 30

Observer(s): Thorstensen & Alper
Institution(s): Dartmouth

Instrument: Modspec + Echelle CCD

Worked for 10 hours (all night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1+ arcsec, Cirrus, Winds Light & Variable
   Mid: Seeing 1 arcsec, Cirrus, Winds Light & Variable
   End: Seeing 0.8 arcsec, Clear, Winds Light & Variable

Observing Summary:

The night began with cirrus, which was very bothersome in the 
bright moonlight and forced us onto bright backup targets.  By
around midnight the cirrus dissipated and the seeing also 
got to be quite good, so we were able to work surprisingly 
faint despite the moon.  No equipment problems.

This report is identical to a spurious  May 1  report I just 
submmitted.  I'll overwrite that tomorrow if it doesn't get
erased.
