*Observing Plan*
 
# standard bias and dome flat sequence
# evening standard stars
# run ObsTac queue
# morning standard stars
 
*Conditions*
 
# Weather at 9 pm: Clear overheal, significant clouds at low elevation
# 10:30pm winds average > 10 mph and we are putting up wind screen
# 11:30pm winds average below 5mph and we remove wind screen
# 04:00am winds average > 10 mph and we are putting up wind screen
 
# Seeing started out at 1.1 during first quarter of the night and improved to 1.0 during the second quarter. At around 12:30am seeing brifly deteriorated to about 2. Seeing improved again at 1am
 
# Seeing according to QR ranged between 0.8-1.2", averaging around 1.0" 
esp
# very cloudy at low elevation early on but improving throughout the night. 
 
 
*Accomplishments*
 
# Afternoon: zeros, dome flat sequence (ugrVRizY).
 
# Evening: Standards (SDSSJ2140-0000, SDSSJ0320-0000) during non-photometric conditions
 
# Overall: Supernova exposures SN-E1 (386229 - 386234), SN-E2 (386235-386240), survey (386241 - 386463).
# Morning: Standards (SDSSJ1227-0000, SDSSJ1227-0000, SDSSJ1227-0000 ) and biases
