Bullet Astrometric & Photometric Monitoring
- SS Cyg (Dwarf Nova)
- BL Lac (Blazar)
- U Her, W And, U And (Mira variables)
- SZ Her, CY Lyr, TZ Lyr (Variable)
- Barnard's Star, Ross 248 (And HH) Groombridge 34, Gliese 1245, HIP 3829, Teegarden's Star (Nearby Stars)
- Session (4.7 hour duration), reasonably clear all night.
- CCD operation of -15 degC (at 62% average cooling). 
- main objectives were to acquire images of selected variable stars and nearby stars for ongoing photometry and astrometry
- opportunity was taken to acquire images of galaxies ARP 222 & 223 and a few faint comets (including 93P/Lovas)
