Objects Session Notes
M31 - Spiral Galaxy (Mosaic) M31 - Extragalactic Nova: M31 2006 14 Astrometric & Photometric Monitoring
- HD 5501/5513 (eclipsing variables)
- SS Cyg (dwarf novae)
- BL Lac (BL Lac blazer)
- U And, W And (mira variables)
- Z And (variable)
- 4.2 hr session, largely operated under automated control - CCD operation of -25 degC (at 76% average cooling). . - main objective was to acquire additional frames to extend a large scale image mosaic of M31 collected during previous session, along with acquisition of images as part of variable star monitoring. - - More Notes -
