*Observing Plan*
# standard bias and dome flat sequence
# evening standard stars
# run ObsTac queue
# end of night standards
# Postnight zeros
*Conditions*
# weather at 4pm CLST: Cloudy and overcast.
# weather at 8pm CLST: Still cloudy, clearer sky on the horizon to the south and west.
# 9:50pm: clear enough to open, but clouds to east and west.
# weather at 12am CLST: 100% cover, nothing to see. Closing now.
# weather at 3am CLST: Still a lot of cloud about, but observing again anyway, seeing 1.3"
# Still some clouds on the horizon at the end of the night. Check standards carefully.
*Accomplishments*
# Afternoon: flat and biases, dome flat done. FlatCheck ok.
# Evening: no standards due to obvious clouds.
# aTmCam and GPS Monitor checked.
# First DES image 483378, 10:00pm, seeing: 2.3"
# image 483382: start of SN field E1
# Stop at midnight, clouds.
# Restart ObsTac at 03:00, image number 483423
# 483447: X3 SN field
# 483482: last DES image.
# Morning standards: SDSSJ0200-0000 (airmass 2), SDSSJ0320-0000 (airmass 1.4), and C26202/HST (airmass 1.1)
