*Observing Team*
 
_DES Observers:_ Rutuparna Das (RM/Obs2), Danny Goldstein (Obs1)
_Telops:_ Claudio Aguilera, Rodrigo Hernandez, Hernan Tirado
_Remote Support:_ 
 
*Observing Plan*
# standard bias and dome flat sequence
# evening standard stars
# run ObsTac queue
# middle-of-night standard stars
 
*Conditions*
# 9:30 (start of observing) - clear sky, windspeed average ~4.5 mph.  Stayed mostly constant through the half night, though wind went down a little.
# Seeing conditions - Median:  1.36, RMS:  .49 (from QR stats page).  DIMM seeing started out at ~1.5, decreasing through the night and ending up at ~.9 by night midpoint.
 
*Accomplishments*
# Afternoon: zeros, dome flat sequence (YziVRrgu).
# Evening: Standards (E3-A, MaxVis, SDSSJ0200-0000).
# Overall:  SN - S2, S1, C1, X2, X3, C3 (392300 - 392323, 392325 - 392347), Wide Survey (392324).
# Middle of Night: Standards (MaxVis, SDSSJ0320-0000)
