Observer Support: 
David James
Night Assistant: 
Claudio Aguilera
Also Present: 
Rodrigo Hernandez
Problems: 

All the night the seeing was bad (generally higher than 1.8 arcsec). We think that this could be related to the fact that low dome temperatures have been always >1.5 degrees Celsius, and oftentimes as muchas a 3 degrees Celsius, cooler than the primary mirror temperature tonight.
