- Mid evening session (3.0 hrs), largely operated under automated control
- Ambient Temperature  4 deg C, gradually falling to 0 deg rby end of session
- CCD operation -20 degC (at 57% average cooling).  
- main objective of the session was  to acquire images of key selected stars for ongoing photometric and astrometric analysis. 
- opportunity taken to acquire images of comet Lulin
