- FG Sge, U Sge, V SgePhotometric Monitoring - Nearby Stars - Groombridge 34
- Short night time session (2.2 hrs).
Initially clear sky with patchy cloud, warm night, cloud developing towards end of sessions- Operated in observatory under semi-automated control. - Ambient Temperature initially 17 deg C, decreasing to 14 deg C by end of observing session. - CCD operation -20 degC (at 90% average cooling). - main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. -
