- Late Evening Session (2.5 hrs), 
- Operated under automated control / remote control. 
- Ambient Temperature  5 deg C, decreasing to 2 deg C, then climbing to 4 deg as clouds developed. Poor seeing.
- CCD operation -25 degC (at 65% 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 certain gallery objects
