Session Notes

M101 - Spiral Galaxy with Supernova 2011fe     Photometric Monitoring - Variables - RX And, U And, Z And, TT Ari, KT Aur, CI Cyg, S Cyg, SS Cyg, BL Lac, CY Lyr, V Sge     Astrometric Monitoring - Nearby Stars - 61 Cyg, Ross 248 (HH And), Groombridge 34, EV Lac, Teegardens Star

- Evening session (2.7 hrs), cloud developing at end of session - Session operated under semi-automated control, with remote monitoring from indoors computer.    - Ambient Temperature: Falling to 0.5°C (minimum)  before climbing to 3.5°C (warm front ?) - CCD operation -25°C (at 61% 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 -
