MDM Observatory 1.3m Telescope Observer's Report for 2006 Apr 05

Observer(s): Aiying Zhou
Institution(s): Missouri State Univ.

Instrument: Apogee Alta U47+ CCD

Worked for 4 hours (part of the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Clear, Winds Calm, before 21:00pm
   Mid: Overcast, Winds Calm
   End: Clear, Winds Calm, after 2:40am

Observing Summary:

At beginning it was clear, but about 21:00pm clouds showed up. 
21:15pm went outside, no star visible in the sky. It's fully 
overcast. Stop observing.
The sky became clear after 02:40am. Pointing to OGLE-109, 
but it took me a long time to identify the target (in fact 
it is in the field but too faint to be visible even at 
exposure time of 180 seconds). This microlensing target is 
the hardest to identify so far for me. So only obtained 
several images at the times near day break. Telescope and 
other instruments worked properly. No problem encountered.
