Session Notes

C/2009 P1 (Garradd) - Comet     M101 - Spiral Galaxy with Supernova 2011fe - Comet P/2006 T1 (Levy) attempt (failed due to out of date ephemeredis) Photometric Monitoring - Variables - CI Cyg, SS Cyg, BL Lac     Astrometric Monitoring - Nearby Stars - None

- Evening session (1.3 hrs), cut short by wind, dew & cloud - a very frustrating session - Session operated under semi-automated control, with remote monitoring from indoors computer.  Major problems with remote connection slow or cutting out.   - Ambient Temperature: 4.5°C (minimum)  - CCD operation -25°C (at 84% average cooling).   - main objective of the session was to acquire images of selected project stars for ongoing photometric analysis and image certain challenge & gallery objects -
