Bullet C/2006 W3 (Christensen) - Comet
Bullet Jupiter & moons
Bullet Moon
Bullet Photometric Monitoring - Variables
- U And, W And, AM CVn,  AM Her, SS Her, U Her
- DY per, GK Per, U Sge, V Sge, ER UMa, SU UMa
Bullet Photometric Monitoring - Nearby Stars
- Barnards Star, Ross 248 (HH And), Groombridge 34
 
- Night time session (2.8 hrs). Initially clear with patchy cloud in Southern Sky. Session cut short by deteriorating sky conditions due to haar/mist and cloud. Very good seeing.
- Operated in observatory under semi-automated control
- Ambient Temperature  Initially 14 deg C falling to 10 deg C by end of session
- CCD operation -20 degC (at 78% average cooling).  
- secondary objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. 
- secondary objective was to test recent software updates including revised focusing logic, and Zenith FWHM extrapolation.
