Quasar PC 1247+340 - Attempted Observation SV CMi - Variable star Astrometric & Photometric Monitoring
- U Gem, (dwarf novae)
- HIP 4429 (suspected variable)
- U And, W And (Mira variables)
- Z And, RZ LMi, U Mon (variables)
- KR Aur, SY Cnc, RR Tau (variables)
- NGC 4151, NGC 2782 (Seyfert galaxies)
- Lalande 21185, Gliese 412, Wolf 359, DX Cnc (Nearby Stars)
- 4.0 hr session. High cloud developing towards end of session. - CCD operation of -25 degC (at 76% average cooling). . - main objective was to acquire images for ongoing photometric and astrometric monitoring of the selected stars - secondary objective was to record a baseline image of the star-field surrounding Quasar PC 1247+340, presented as a Deep Sky challenge in April 2007 edition of Astronomy Now - More Notes -
