Objects Session Notes
C/2007 N3 (Lulin) - Comet 116P/Wild - Comet 144P/Kushida - Comet 85P/Boethin - Comet Astrometric & Photometric Monitoring - U Gem (dwarf nova)
- RX And, TT Ari, HR Aur, KR Aur, RZ LMi, U Mon, CN Ori, CZ Ori, FO Ori, FU Ori, NC Ori, DY Per, RR Tau (variables)
SY Cnc attempt (aborted due to cloud ?)
- Mid evening session (3.0 hrs), largely operated under automated control - Ambient Temperature 4 deg C, gradually falling to 0 deg rby end of session - CCD operation -20 degC (at 57% average cooling). - main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. - opportunity taken to acquire images of comet Lulin and a few other fainter comets
