Objects Session Notes
168P/Hergenrother - Comet C/2012 K5 (LINEAR) - Comet C/2012 S1 (ISON) - 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), 6Groombridge 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 -
