Objects Session Notes
King 2 - Open Cluster / Asterism 2007 XH16 - Near Earth Asteroid (NEA) / Minor Planet NGC 7510 - Open Cluster NGC 7261 - Open Cluster 8P/Tuttle - Comet Astrometric & Photometric Monitoring
- SS Cyg, U Gem (dwarf nova)
- BL Lac (Blazar)
- W And (mira variables)
- CY Lyr, TZ Lyr, TT Ari, RZ LMi, RX And (variables)
- RU Peg, DY Per (variables)
- Gliese 725 (Nearby Stars)
- Evening session (7.0hr). Poor transparency - Problem performing automated short mapping job using new TPoint Model. Manually controlled mapping was required instead. - CCD operation of -25 degC (at 68% average cooling). - -main objectives were to acquire images of certain selected stars of ongoing photometric and astrometric analysis, and follow up images of comet 8P/Tuttle -opportunity was also taken to acquire gallery images of certain deep sky objects, including open clusters in Cepheus

2007 XH16 is a 565m diameter asteroid which is
due to pass by the earth on 2007-12-24 at a distance of 8.1 lunar distance
(LD).
A sequence of images of 2007 XH16 were recorded streaking through a star field
in Eridanus.
(More images of 2007 XH16 from
2007-12-24/25 at near closest approach)
