*Observing Plan*
 
# standard bias and dome flat sequence
# evening standard stars (SKIPPED due to clouds)
# run ObsTac queue
# morning standard stars and bias
 
*Conditions*
 
#10:30 PM There were quite a few clouds at the start of the night, so we skipped standards. Clouds cleared up quite quickly though.
#12:30 AM There have been no further clouds, but seeing has been up and down all night. ObsTac has gone back and forth between survey and supernovae multiple times.
#2:30 AM Winds picked up and screen just went up. 
#4:00 AM Winds have stayed strong, we closed all the louvers. Seeing has gotten better and we've been on Survey alone since 3:15.
 
#End of night: Ended the night with a couple hours of great seeing and doing Survey. Before that, Obstac went back and forth between Survey and supernovae due to seeing. Otherwise ended up being a very very clear night despite clouds at sunset.
 
 
*Accomplishments*
 
# Afternoon: zeros, dome flat sequence (ugrVRizY).
 
# Evening: NO STANDARDS
# Overall: Supernova: SN-X1 (387378-387383), SN-X2 (387400-387405), SN-X3 (387406-387419, 387425-387436), SN-S1 (387442-387447), SN-C3 (387466-387473),  Survey: (387384-387399, 387420-387424, 387437-387441, 387448-387465, 387474-387544)
# Morning: Standards (SDSSJ1227-0000, MaxVis, SDSSJ0933-0000) and biases
