Objects Session Notes
C/2006 M4 (Swan) - Comet BL Lac - Active Extragalactic Object (Blazer) P/2006 HR30 (Siding Spring) - Comet Astrometric & Photometric Monitoring
- HD 5501/5513 (eclipsing variables)
- SS Cyg (dwarf novae)
- Z And (variable)
- BL Lac (BL Lac blazer)
- U And, W And, U Her (Mira variables)
- 2.6 hr session, largely operated under automated control - CCD operation of -20 degC (at 70% average cooling). Ambient temperature 7 deg. - session terminated early due to developing cloud - main objectives were to acquire BVRI images of Mira stars (U Her, U And, W And) as part of ongoing photometric studies, together with follow-up images on C/2006 M4, BL Lac and M31 Nova (2006 14) - attempts made to image M31 Nova (2006 14), Palmor 13, and comet 4P/Faye were spoiled by cloud - - More Notes -
