Objects Session Notes
C/2007 N3 (Lulin) - Comet NGC 2939 - Spiral Galaxy with Supernovae 2009ao C/2009 T2 (Cardinal) - Comet Astrometric & Photometric Monitoring - U Gem (dwarf nova)
- BL Lac (blazar)
- RX And, Z And, TT Ari, HR Aur, CC Cnc, R CrB, CN Ori, CZ Ori, FO Ori, FU Ori, DY Per, GK Per, ER UMa (variables)
- Evening session (3.2 hrs), largely operated under automated control - Ambient Temperature initially 2 deg C, gradually falling to -1 deg C by end of session - CCD operation -25 degC (at 64% 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 - Notes from 2009-03-05 (Flats History)
