Night Assistant: 
Claudio Aguilera
Problems: 

Power fail at 00:57, back on sky after 7 minutes.

Comments: 

Photometric night, unstable high altitude seeing at the start, sttled down later.    DIMM worked all night, thanks!

Same as last night, I zapped the Exposure Table GUI before starting.  I had to reload the Oberver Console once, at 1 am.  

I am basically following the same field all night, the script uses absolute positions with small dithers.   The telescope pointing is very good, every time I check it's within a very few arcsec (2-5).   Dec -19 deg.
