Objects Session Notes
2006 VV2 - Minor Planet IC 4593 - Planetary Nebula ("White-Eyed Pea Nebula") Astrometric & Photometric Monitoring
- U Gem, (dwarf novae)
- U And, W And, U Her (Mira variables)
- Z And, RZ LMi, U Mon, ER UMa, SU UMa, UX UMa (variables)
- KR Aur, SY Cnc, RR Tau (variables)
- NGC 4151, NGC 2782 (Seyfert galaxies)
- Groombridge 1830, Gliese 1245 (Nearby Stars)
- 5.1 hr session. - CCD operation of -25 degC (at 78% average cooling). . - main objective was to acquire images of the small minor planet 2006 VV2 which was passing close by the earth. - secondary objective was to record on images of selected stars for ongoing photometric monitoring - opportunity was also taken to acquire images of HH 34, IC 4593, NGC 4030, CVn AM - More Notes -
Note the slight wobble in trace of MPL 2006 VV2
is due to small residual periodic error of +/-2.5 arc secs in the LX200 scope,
as shown by simulation
