Objects Session Notes
Hedgehog / Unexpected Visitor to Observatory Venus M94 - Spiral Galaxy Comet C/2007 E2 (Lovejoy) Moon Astrometric & Photometric Monitoring
- U Her (Mira variables)
- Aur KR, Cnc SY, CVn AM, CVn Y, RZ LMi,
SY Cnc, And Z, ER UMa, SU UMa, UX UMa (variables)
- NGC 4151, NGC 2782 (Seyfert galaxies)
- BL Lac (Blazar), 3C 273 (Quasar)
-Barnards Star, Gliese 412, Gliese 1245, Groombridge 34,
Groombridge 1618, And HH (Nearby Stars)
- 6.3 hr session, cloud, some clear patches - CCD operation of -20 degC (at 89% average cooling). . - main objective was to acquire images of the Moon at 75% phase, followed by images selected stars for photometric analysis. In the event developing cloud meant that only images of the Moon were acquired before the observatory was closed. - More Notes -
