Problems: 

# RASICAM pictures look too optimistic (too much sky area is coded dark)
# LN2 RIO communication issue resulted in detectors warming by 5 degrees.  Failure occurred 00:20, after the afternoon flats had finished.  Tempertures recovered and stable after a couple hours.

*Observing Plan*
 
# standard bias and dome flat sequence
# evening standard stars
# run ObsTac queue
# morning standard stars
 
*Accomplishments*
 
# Afternoon: zeros, dome flats (ugriz).
# Night lost to clouds.
# Airmass limit for SN fields changed from 1.3 to 1.5.
# Review the various observing check lists and updated the wiki accordingly. 
# Overall: Exposures, all calibration, extend from 231137 to 231269.  Use only 231168 to 231269.
