- Late Evening session (2.5 hrs duration). - Session operated under semi-automated control, with remote monitoring from indoors computer. - Ambient Temperature: Initially dropping from +1.0°C down to -2.5°C, - CCD operation -30°C (at 67% average cooling). - main objectives of the session were to acquire images of selected project stars for ongoing photometric and astrometric analysis. Opportunity was taken to acquire fimages of a number of open clusters in Gemini -
