Session Notes

Moon     IC 607 - Spiral Galaxy (ARP 43) IC 2497 - Spiral Galaxy (Hanny's Voorwerp)  (attempt)     M95 - Spiral Galaxy with SN 2012aw M101 - Spiral Galaxy with Supernova 2011fe     UGC 8613 - Spiral Galaxy (ARP 33)     Photometric Monitoring - Variables - R CrB, CY Cyg, SS Cyg, U Gem, BL Lac, RZ LMi, CY Lyr, DY Per, GK Per, ER UMa     Astrometric Monitoring - Nearby Stars - Gliese 1111 (DX Cnc), 61 Cyg

- Evening session (3.4hrs duration).  - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Ambient Temperature: -2.0°C (minimum)  - CCD operation -30°C (at 76% average cooling).   - main objectives of the session were to acquire images of selected project stars for ongoing photometric and astrometric analysis.  -
