MDM Observatory 2.4m Telescope Observer's Report for 2006 Oct 27

Observer(s): R.J. Assef, K. Schlesinger
Institution(s): OSU

Instrument: CCDS, RETROCAM

Worked for 12 hours (all night)
Conditions were Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Seeing 2.5 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 1.7 arcsec, Clear, Winds Light & Variable
   End: Seeing 1.2 arcsec, Clear, Winds Light & Variable

Observing Summary:

There appeared to be a thin layer of cloud that affected our 
seeing early on in the night; it was around 2.5 . Over the course 
of the night, our seeing improved dramatically to around 1 . 
We tried to observe an object near the horizon with an airmass 
of around 3; the guider did not work for this region of the sky
so we were forced to wait until the object (GRB 061028) rose 
higher in the sky to observe it. We also had a small problem with 
the TCS display. The AutoDome was switched on and the display 
showed  Auto Dome On.  However, when we were trying to observe 
near the horizon, we frequently got an error saying the 
Auto Dome was off in the region where it says  Coordinates 
received,  etc. This didn't actually reflect what the dome 
was doing, as it moved in accordance to the position of the 
telescope.
