*Observing Plan*
# standard bias and dome flat sequence
# evening standard stars
# run ObsTac queue
# morning standard stars and bias
 
*Conditions*
# Conditions have been pretty constant for most of the evening, 
wind at 10mph, so windscreen is up at 10:10, for an hour and the back up again at 4:57am.
# Variable seeing throught the night, observations started with seeing on the DIMM between 1.-1.3 and get higher ~1.70 for about half an hour, then back again to 0.7-1.1, at the end of the night, seeing remained around 0.67. Varing FWHM 0.78-1.55 with a median value of 1.11 and RMS 0.16 from quickRed. 
# No clouds.
 
*Accomplishments*
# Afternoon: zeros, dome flat sequence (YziVRrgu).
 
# Evening: Standards (SDSSJ2300-0000 230000+000000 secz 1.7),(SDSSJ0000-0000 000000+000000 secz 1.4), (SDSSJ0200-0000 020000+000000 secz 1.2).
