Session Notes

M101 - Spiral Galaxy with Supernova 2011fe     NGC 3239 - Irregular Galaxy (ARP 263) with Supernova 2012A Photometric Monitoring - Variables - FO And, RX And, U And, W And, Z And, TT Ari, BL Lac, RZ LMi, DY Per, GK Per - RR Tau attempt (failed due to wind/cloud)     Astrometric Monitoring - Nearby Stars - Ross 248 (HH And), EV Lac - Wolf (CN Leo) and DX Cnc attempts (failed due to cloud/poor seeing)

- Evening session (2.2 hrs duration).  - Session parts operated under semi-automated control, with remote monitoring from indoors computer.    - Ambient Temperature: -5°C (minimum)  - CCD operation -30°C (at 59% average cooling).   - main objective of the session was to acquire images of selected project stars for ongoing photometric and astrometric analysis.  -
