Objects Session Notes
Comet 17P/Holmes Astrometric & Photometric Monitoring
- SS Cyg (dwarf nova)
- BL Lac (Blazar)
- RX And, TT Ari (variables)
- CY Lyr, TZ Lyr (variables)
- HH And, Groombridge 34 (Nearby Stars)
- (unsuccessful attempts at U And, W And, Z And due to cloud)
- Evening session (3.0hr), thin cloud / poor transparency CCD operation of -25 degC (at 72% average cooling). - main objective of the session was to acquire follow up images of the comet 17P/Holmes -secondary objectives were to acquire images of certain selected stars of ongoing photometric and astrometric analysis
