Bullet Variable Stars
Bullet Photometric Monitoring - Variables
- FS Aur, SY Cnc, R CrB, AM CVn, U Gem, RZ LMi, DY Per, GK Per 
Bullet Astrometric Monitoring - Nearby Stars
- CN Leo, DX Cnc
- Late Evening session (2.5 hrs duration). 
- Session operated under semi-automated control, with remote monitoring from indoors computer.  
- Ambient Temperature: Initially dropping from +1.0 deg C down to -2.5 degC,
- CCD operation -30 degC (at 67% average cooling).  
- main objectives of the session were to acquire images of selected project stars for ongoing photometric and astrometric analysis. Opportunity was taken to acquire fimages of a number of open clusters in Gemini
