*Observing Plan*
 
# standard bias and dome flat sequence
# new nightly sequence of dark images
# evening standard stars
# run ObsTac queue
# morning standard stars and bias
 
*Conditions*
 
#09:00pm Clear sky. Wind speed averages between 5-6 mph.
#12:02am Wind picked up and averages > 10 mph. Windscreen is going up.

# Seeing conditions: Median: .94 RMS: .23 (from QR stats page)  Seeing jumped up and started fluctuating a lot at around 3:15am CLST (perhaps due to a rise in humidity at that time?).
 
*Accomplishments*
 
# Afternoon: zeros, dome flat sequence (YziVRrgu), new nightly sequence of darks.
# Evening: Standards (MaxVis, SDSSJ2300-0000, SDSSJ0200-0000)
# Overall: SN (389430 - 389453), Survey (389454 - 389637)
# Morning: Standards (SDSSJ1227-0000, SDSSJ0933-0005) and biases
