Objects 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C/2009 P1 (Garradd) - Comet M101 - spiral galaxy with supernova 2011fe Comet P/2006 T1 (Levy) attempt (failed due to out of date ephemeredis) Variable Stars Photometric Monitoring - Variables - CI Cyg, SS Cyg, BL Lac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 deg C (minimum) - CCD operation -25 degC (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 -
