Cloud was found to have cleared by 3.30am and allowed a Pre-Dawn session .
- Ambient Temperature 11-12degC (late evening), 7-9 deg C (pre-dawn) 
- CCD operation of -20 degC 
(at 81% average cooling).  
- main objective was to acquire images of key selected stars for ongoing photometric and astrometric analysis. 
- opportunity take to acquire images of selected open clusters from Herschell 400 Catalog
