*Observing Plan*
# standard bias and dome flat sequence
# evening standard stars
# run ObsTac queue
# end of night standards
*Conditions*
# weather in afternoon: 4pm (local): thin clouds; ~30% cloud cover
# weather after sunset: 9pm (local): thin clouds near the horizon on the west.
# weather at 1am (local): some thick clouds near the horizon on the west.
# weather at 3am (local): overcast. Telescope closed at 3:10am.
# weather didn't improve after 3:10am.
*Accomplishments*
# Afternoon: flats and biases, (ugrizYVR) dome flats done, flatCheck ok
# Evening: Beginning of night standards are SDSSJ2300-0000 (airmass 1.8), SDSSJ2140-0000 (airmass 1.3) and E8-A (airmass 1.0).
# aTmCam and GPS Monitor checked.
# ObsTac ran until 3:10am (local).
# Survey Exposures 481755-481940 in grizY bands, all wide fields.
*Problems tagged as Synopsis_Problem*
# Telescope closed at 3:10am (local) due to heavy clouds.
*Minor Problems and Relevant Information*
# Rasicam is still unoperational. Used SASCA instead.
*Notes for Data Management*
# Due to clouds and high seeing, it might be worthwhile to declare most exposures as bad.
