Session Notes

C/2009 P1 (Garradd) - Comet     M101 - Spiral Galaxy with Supernova 2011fe     Photometric Monitoring - Variables - RX And, U And, TT Ari, CI Cyg, S Cyg, SS Cyg, BL Lac, CY Lyr, DY Per, GK Per - W And, Z And attempts (failed due to cloud)     Astrometric Monitoring - Nearby Stars - 61 Cyg, Ross 248 (HH And), Groombridge 34

- Evening session (2.3 hrs), cut short due to cloud - Session operated under semi-automated control, with remote monitoring from indoors computer.  - Ambient Temperature: 5.5°C (minimum)  - CCD operation -20°C (at 63% average cooling).   - main objective of the session to obtain follow-up images of bright supernovae in nearby galaxy M101 secondary objective was to image project stars for ongoing photometric analysis -
