- Evening session (3.1 hrs duration).  - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Ambient Temperature:  -3.0 degC minimum - CCD operation -30 degC (at 63% average cooling).   - main objectives of the session were to acquire images of a number of Herschel 400 objects in Ursa Major.  Secondary objective was to acquire images selected project stars for ongoing photometric and astrometric analysis.  -
