Session Notes

168P/Hergenrother - Comet 260/P McNaught - Comet C/2012 K5 (LINEAR) - Comet    Photometric Monitoring - Variables - R CrB, CY Cyg, SS Cyg, U Her, DY Per, GK Per Astrometric Monitoring - Nearby Stars - None   - 61 Cyg attempt failed (due to poor visibility)

- Late Evening session (4.1 hrs duration). Wind effected. - Session operated under semi-automated control, with remote monitoring from indoors computer.   (Power-Line networking) - Ambient Temperature: -4.0°C (minimum) - CCD operation -30°C (at 58% average cooling).   - main objectives of the session were to perform further software testing and to acquire images of selected project stars for ongoing photometric and astrometric analysis. Opportunity also taken to image some deep sky objects. -
