- Early evening  session (4.6 hrs), - Session operated under semi-automated control, with remote monitoring from indoors computer.  - Ambient Temperature: Initially 7.0°C falling steadily to 3.0°C  (minimum) by session end. - CCD operation -25°C (at 73% average cooling).   - main objectives of the session was to acquire images of selected project stars for ongoing photometric analysis.
