Objects Session Notes
C/2006 M4 (Swan) - Comet TrES-2 - Parent Star to exosolar planet M31 - Extragalactic Nova: M31 2006 14 Globular clusters in M31 BL Lac - Active Extragalactic Object (Blazer) 4P/Faye - Comet Astrometric & Photometric Monitoring
- Barnard's Star (nearby star)
- SS Cyg (dwarf novae)
- HD 5501/5513 (eclipsing variables)
- Z And (variable)
- BL Lac (BL Lac blazer)
- U And, W And (Mira variables)
- 3.3 hr session, largely operated under automated control - CCD operation of -25 degC (at 87% average cooling). Ambient temperature rising during session, due to advance of warm front /developing cloud. (CCD camera cooling 80% at start of session, increasing to 90-95% by end) - main objectives where to a acquire sequence of images of HD 5501/HD 5513 and SS Cyg as part of ongoing photometric studies, and to acquire baseline images of GSC 3549:2811 (extrasolar planet sol to TrES-2) - opportunity was also taken to acquire images of newly discovered nova in M31 (2006 14) - - More Notes -
