MDM Observatory 1.3m Telescope Observing Report for 2010 May 08

Observer(s): Uthas
Institution(s): Columbia

Instrument: Templeton/direct

Worked for 7 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.5 arcsec, Clear, Winds Calm
   Mid: Seeing 1.3 arcsec, Clear, Winds Calm
   End: Clear, Winds Calm

Observing Summary:

Multiple integration suddenly failed after 622 frames....  (set to : go 10000).
Unfortunately this happened in the early morning when the observer 
was very tired, absorbed in research and thought she could just keep 
an eye on the guider to scan for weather conditions. 
I lost 2 hours (and will probably in the future religiously watch that the 
integration is going).  

error message is included below: 

ccd_aread: wrong aio finished; expected 0.  This is bad.
*** Error encountered in asynchronous read: data suspect
Failed, return code = 0, elapsed = 1.344000
