*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 ~6 mph. Stayed mostly constant through the half night.

# Seeing conditions - Median: .90, RMS: .14 (from QR stats page). DIMM seeing was between ~.5 and ~.7 while the DIMM was reporting.

*Accomplishments*

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

# Evening: Standards (SDSSJ2300-0000, MaxVis, SDSSJ0200-0000).

# Overall: Wide Survey (392629 - 392740).

# Middle of Night: Standards (SDSSJ0320-0000, MaxVis)

*Problems tagged as Synopsis_Problem*

*Minor Problems and Relevant Information*

#DIMM stopped reporting between 11:20 - 1:20 CLST.

#We had a shutter error that took longer than usual to fix. See below (under "Other selected logbook entries") for details.

*Notes for Data Management*

#Exposure 392702 was not taken due to the shutter error.

#Exposure 392703 is a zero taken for testing purposes after the shutter was reset.
