- Night time session (3.8 hrs). Clear skies. Some NLC in extreme northern skies before dawn - Operated in observatory under semi-automated control for first part of session, then with automated control / remote monitoring - Ambient Temperature initially 12 deg C, decreasing to 8 deg C by end of observing session. - CCD operation -20 degC (at 71% average cooling). - main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. - opportunity taken to acquire images of Jupiter, Comet 22/P Kopff and a number of deep sky objects, including Caldwell 57 (NGC 6822)
