*Observing Plan*

# standard bias and dome flat sequence

# evening standard stars (inverted airmass order to easily hit ToO)

# NEOwise ToO

# run ObsTac queue

# morning standard stars

*Conditions*

# Weather at 9:30PM: Clear

# 12:30AM Winds have been hovering around 8mph for over an hour, but not gone higher. Kept windscreen off.

# 1:30AM Winds have died down the past hour. A few wispy clouds in multiple directions and overhead, but very thin. Most of sky looks clear.

# 3:30 AM Seeing has been good (less than 1" most of the night), wind has been low (5-6 mph). A few more clouds on the horizon now, but overhead still looks quite clear.

#End of night: seeing has been good all night. Never needed wind screen. Clouds were very minimal.

*Accomplishments*

# Afternoon: zeros, dome flat sequence (ugrVRizY).

# Evening: Standards (SDSSJ0100-0000, SDSSJ2140-0000, E8-A)

# Overall: NEOwise ToO: NOO7880 (386625-386629), Supernova SN-S2 (386630-386635), Survey (386636-386854)

# Morning: Standards (SDSSJ1227-0000, SDSSJ1048-0000, SDSSJ0843-0000 ) and biases
