_DES Observers:_ Tomek Kacprzak, David Gerdes
_Telops:_ Claudio Manuel Hernandez
_Daytime Support:_ Javier Rojas
 
*Observing Plan*
 
# standard bias and dome flat sequence
# evening standard stars
# run ObsTac queue
# middle-of-night standards
# handover to community observer
 
*Conditions*
 
# weather in afternoon: 4pm (local): clear
# weather after dinner: 7pm (local): clear, low haze, humidity 62%
# weather at 10 deg twilight: 21:30 (local): clear, low haze, humidity 66%
# weather summary: 2am (local): Clear, seeing about 1" in r-band
# Seeing conditions: 1.10 +/- 0.15"
# Wind conditions: low, <8mph
 
*Accomplishments*
 
# Afternoon: zeros done 279664-279672 and 279748-279756;  279673-279747 (ugrizY) dome flats done, checked all ok. Note u-band exposures changed to 150 seconds (was 20), per David James email. Power also reduced from 100% to 80%, so counts/sec even lower than usual.
# Evening standards: 279661-279777
