- HR Aur, KR Aur, SY Cnc, DY Per, GK Per (variables)
- Groombridge 1618, Groombridge 1830, Lalande 21185 (Nearby Stars)
- SS Cyg attempt (failed due to cloud)
- Late Evening Session (2.5 hrs), - Operated under automated control / remote control. - Ambient Temperature 5 deg C, decreasing to 2 deg C, then climbing to 4 deg as clouds developed. Poor seeing. - CCD operation -25 degC (at 65% 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 certain gallery objects - -
