*Observing Plan*
# standard bias and dome flat sequence
# evening standard stars
# run ObsTac queue
# middle-of-night standard star
 
*Conditions*
# Conditions have been pretty constant for most of the evening, with low to medium wind.
QR Median seeing is .8, and RMS is .09. DIMM seeing was listed between ~.5 and ~.8.
# No clouds.
 
*Accomplishments*
# Afternoon: zeros, dome flat sequence (YziVRrgu).
# Evening: standards SDSSJ2300-0000 (230000+000000  secz 1.9),SDSSJ0000-0000 (000000+000000  secz 1.5),SDSSJ0320-0000 (032000+000000  secz 1.2).
