Observer Support: 
Catherine Kaleida
Night Assistant: 
Roberto Aviles
Problems: 

Heavy clouds came in around 4:15 and the quality of the data diminished.

At the same time roberto reported that there was a possible problem with the liquid Nitrogen cooling system for the CCDs. Given that the data was already of poor quality and that there was only an hour left of observations we decided to end the night so dedicated focus could be given to the engineering problem at ~5am.
