Objects Session Notes
Comet 17P/Holmes Astrometric & Photometric Monitoring
- RX And, TT Ari, Z And, U Mon (variables)
- W And (Mira Variable)
- (unsuccessful attempts at U Gem due to dawn light)
- Morning session (2.5hr), cold, frosty CCD operation of -25 degC (at 71% average cooling). - main objective of the session was to acquire an follow up images of recently erupted comet 17P/Holmes
