MDM Observatory 2.4m Telescope Observing Report for 2015 Mar 23

Observer(s): Kay/Moran
Institution(s): Columbia

Instrument: 4K

Worked for 9.0 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.1 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 1.3 arcsec, Clear, Winds Light & Variable
   End: Seeing 1.3 arcsec, Clear, Winds Light & Variable

Observing Summary:

Observing generally went well.  Seeing was decent most of the night (~1.0 - 1.3 arsec).
Not sure if it was truly photometric, but we saw no evidence of clouds.  The
temperature changed quite a bit and never seemed to be steady.  So, the focus
changed a lot.  We were slowed a bit by the fact that the instrument or prospero
didn't behave correctly when a subarray was selected.  So, the focusing couldn't
be done with short readout times.  The data are quite good.
