MDM Observatory 2.4m Telescope Observing Report for 2013 Oct 06

Observer(s): Fesen
Institution(s): Dartmouth

Instrument: CCDS

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

Seeing and Weather:
   Beg: Seeing 2-3 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 1.5-2 arcsec, Clear, Winds Light & Variable
   End: Seeing 1.0 arcsec, Cirrus, Winds Calm

Observing Summary:

Highly variable seeing during the first half of the night.
Started off near 1 arcsec but grew to 2, 3,and even 4 arcsec
at times. Became much better the second half, ending in near
subarcsec seeing conditions. Light clouds/cirrus during
the second half of the night, possibly related to the improved
seeing.

The link to the CCDS acquistion camera was lost after 1 hour
of observing and was traced to a loose USB connection at
the SBig camera's USB dongle (both amber and green lights have to
be on before it can establish a link).
This happened a second time following a slit rotation but was
quickly fixed.
