Session Notes

M101 - Spiral Galaxy with Supernova 2011fe     UGC 4985 - Spiral Galaxy UGC 6132 - BL Lac type quasar (Markarian 421) Photometric Monitoring - Variables - FO And, RX And, Z And, TT Ari, FS Aur, KR Aur, CY Cmi, AM CVn, SS Cyg, U Gem, BL Lac, RZ LMi, U Mon, CN Ori, FO Ori, FU Ori, GK Per, RR Tau, SU Tau - RS CVn, ER UMa attempts (failed due to wind/cloud)     Astrometric Monitoring - Nearby Stars - Groombridge 1618

- Evening session (6.4 hrs duration). Mixed sky conditions with some wind. Session ended when cloud developed - Session parts operated under semi-automated control, with remote monitoring from indoors computer.    - Ambient Temperature: -5°C (minimum)  - CCD operation -30°C (at 60% average cooling).   - main objective of the session was to acquire images of selected project stars for ongoing photometric and astrometric analysis.  -
