- AM Her (polar variables)
- Ross 248 (HH And), Barnards Star, Groombridge 34, HIP 3829 (Van Maanen's Star), Teegardens Star (nearby stars)
Time Series
- EV Lac, SS Cyg
- RR Tau attempts (failed due to cloud/dawn)
- QQ Vul attempt (star drift)
- 61 Cyg attempt (failed due to cloud)
- All night session (10.0 hrs), operated under automated control - Ambient Temperature 3 degC (minimum) - CCD operation of -20 degC
(at 66% average cooling).- main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. - a secondary objective, to test revised routine for automated guiding between frames, was not possible due to early termination of the session. -
