CCD Images - Session 523 (2012-11-08)

Objects Session Notes
Bullet C/2012 K5 (LINEAR) - Comet
Bullet 168P/Hergenrother - Comet
 
Bullet Variable Stars
Bullet 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)

Bullet 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 deg C (minimum) , before climbing to +6.0 degC as warm front approached, and cloud developed with light rain starting falling at end of session. 
- CCD operation -30 degC (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
