- Night session (1.9 hr). 
- Operated in Observatory under manual and semi-automated control. Later operated under automated control with remote monitoing
- Ambient Temperature  10 deg C
- CCD operation -20 degC (at 73 % average cooling).  
- main objective of the session was to acquire images of key selected stars for ongoing photometric and astrometric analysis.

136199 Eris - Dwarf Planet ( 2003 UB313)

MPL 2003 UB313 attempt  
(Cetus, altitude 23 deg, airmass 2.5) 
With predicted magnitude of 18.7, Eris would have been too faint 
to seen in this image (mag limit +18). 
Glare from mag 9 star would also have been a problem
