MDM Observatory 2.4m Telescope Observing Report for 2014 Jun 19

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

Instrument: Modspec + Echelle CCD

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

Seeing and Weather:
   Beg: Seeing 0.9 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 0.9 arcsec, Clear, Winds Light & Variable
   End: Seeing 1.5 arcsec, Clear, Winds Light & Variable

Observing Summary:

A nice night, clear and warmer than before.  Seeing started out
well but degraded later in the night.  

We had an odd problem with Owl, but it was almost certainly 
operator error, though there may actually be a problem.  
At the start of the night we noticed that the number of lines and 
columns didn't match our notes, so we reset the subarray to what 
we thought was right.  A little while into the night we noticed
the wavelength coverage was slightly off, which led us to spend
an hour trying to get everything reset correctly.  We had
been using an offset subarray center -- dCol = 1090 and 
dRow = 1020 -- but this did not appear to  take  when we
reset it, although it's difficult to tell since Owl does not
record the subarray in the header.  After about an hour
of fooling around, we went ahead and used what we had.  

We are taking new flats into the morning.  They should be done
when the staff comes in, so whoever gets here first can please
turn off the flat lamp ... thanks!
