- Early morning session (3.9 hr). slight wind at times, condensation on front corrector lens by end of session.
- Session operated under semi-automated control with remote monitoring
- Ambient Temperature:  Initially 3.0 degC falling to 1.0 degC minimum by end of session
- CCD operation -25 degC (at 61% average cooling).  
- main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis. 
- opportunity taken to acquire images of the dwarf planet Makemake.
