Session Notes

M101 - Spiral Galaxy with Supernova 2011fe     Photometric Monitoring - Variables - R CrB - CI Cyg, S Cyg, SS Cyg failed due to wind)     Astrometric Monitoring - Nearby Stars - None - 61 Cyg attempt (failed due to wind)

- Evening session (1.3 hrs), windy, cut short due to wind/cloud - Session operated under semi-automated control, with remote monitoring from indoors computer.  - Ambient Temperature: 8.5°C (minimum)  - CCD operation -20°C (at 69% 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 -
