- Evening  session (5.8 hrs). - Session operated under semi-automated control, with remote monitoring from indoors computer.  - Ambient Temperature: -3.0°C  (minimum) - CCD operation -30°C (at 63% average cooling).   - main objectives of the session was to acquire images of selected project stars for ongoing photometric analysis. - Notes from 2011-01-20 (start-up problems)
