MDM Observatory 2.4m Telescope Observing Report for 2010 Jun 27

Observer(s): Tobin and Hsu
Institution(s): Michigan

Instrument: TIFKAM

Worked for 8.5 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 1.5 arcsec, Clear, Winds Calm
   Mid: Seeing 1.0 arcsec, Clear, Winds Calm
   End: Seeing 1.0 arcsec, Clear, Winds Calm

Observing Summary:

Most of the night went quite well, observed 4 targets in Ks,
H, and H_2 bands. At about 4:45 am the top right quadrant of
detector started giving garbage; see the open DS9 window. We
rebooted the IC computer as a first attempt to fix this, the 
problem persisted and we didn't take further action since it was
the end of the night. I presume that power cycling the HE box
might fix this.
