Objects Session Notes
Barnard's Star (HIP 87937) - Nearby Star (5.94 ly) Astrometric & Photometric Monitoring - SS Cyg (dwarf nova)
- V2491 Cyg (nova)
- BL Lac (blazar)
- RX And, EV Lac (variables)
- Barnards Star, EV Lac, Groombridge 34, Ross 248 (Nearby Stars)
- Late evening session (1.6hr) - again cut short by developing cloud. - Warm night, ambient Temperature 15 degC - CCD operation of -15 degC
(at 86% average cooling).- main objective was to acquire images of certain selected stars for ongoing photometric and astrometric analysis. - cloud unfortunately developed before being able to image a planned set of mira variables (U Her, U And, W And)
Continued monitoring of Barnard's Star shows good results with well defined proper motion and parallax combining to give a clear annual wobble in the star's path, relative to background stars.
