- Gliese 412,Groombridge 1618, Groombridge 1830, Lalande 21185, HIP 67593 (Nearby Stars)
- Early morning session (4.7hr), operated under automated control for majority of session. CCD operation of -25 degC (at 54% average cooling). -main objectives were to acquire images of certain selected stars of ongoing photometric and astrometric analysis -opportunity was also taken to acquire a mosaic image of M42 in Infrared (I) Filter and images of 3 faint comets.
