Session Notes

168P/Hergenrother - Comet C/2012 K5 (LINEAR) - Comet   Photometric Monitoring - Variables - RX And, Z And, TT Ari, CI Cyg, SS Cyg, BL Lac, TZ Lyr   Attempts: U And failed (wind),  CY Lyr failed (wind/poor sky),  GK Per failed (Cloud)     Astrometric Monitoring - Nearby Stars - Ross 248 (HH And), Groombridge 34, Teegardens Star Attempts: 61 Cyg failed (poor sky)

- Evening session (2.9 hrs duration).  Mixed conditions, wind affecting some images , cloud affecting others. - Session operated under semi-automated control, with remote monitoring from indoors computer.   (Power-Line networking) - Ambient Temperature: Initially falling to +2.5°C (minimum) , before climbing to +6.0°C as warm front approached, and cloud developed with light rain starting falling at end of session.  - CCD operation -30°C (at 70% average cooling).   - main objectives of the session were to acquire images of selected project stars for ongoing photometric and astrometric analysis, and to image a number of deep sky objects  -
