Objects Session Notes
GK Per - Nova (1901) U Gem - Dwarf Nova Variable U Mon - Variable Beta Mon / Struve 919 - Multiple Star NGC 1907 - Open Cluster RZ LMi - Cataclysmic variable star (ER UMa type) DV UMa - Cataclysmic variable star (binary eclipsing, UGSU type) ER UMa - Cataclysmic variable star (ER UMa type) Astrometric & Photometric Monitoring
- SS Cyg (dwarf novae)
- HIP 4429 (suspected variable)
- HIP 4429 (suspected variable)
- U And, W And (Mira variables)
- Z And (variables)
- BL Lac (BL Lac blazer)
- 5.5 hr session cut short by deteriorating sky conditions - CCD operation of -25 degC (at 69% average cooling). . - the other main objective was to acquire images for photometric monitoring of the variables stars U And, W And, SS Cyg and a suspected variable HIP 4429. - opportunity was taken to acquire some exploratory images of U Gem, RZ LMi and DV UMa which may be added to future variable star monitoring. - More Notes -
