*Observing Team*

_DES Observers:_ Cristina Furlanetto, Suk Sien Tie, David James
_Telops:_ Hernan Tirado, Rodrigo Hernandez
_Remote Support:_ ---

*Observing Plan*

# standard bias and dome flat sequence
# evening standard stars
# run ObsTac queue
# end of night standards
# defocus nightly

*Conditions*

# weather in afternoon: 4pm (local): Heavy clouds all around
# weather after sunset: 8pm (local): The sky cleared up a little -- thin streaks of clouds overhead, clear on south west and cloudy on north east.
# weather at 1am local: cirrusy on south and north but clear overhead.
# weather at 3:30am local: Sky cleared up but seeing still hovers around 1.5".

*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).
# aTmCam and GPS Monitor Checked.
# ObsTac completed, although in slightly worse seeings.
# Survey Exposures 480893-481087 in grizY bands including SN fields: E1 (griz), E2 (griz), C1 (griz), C2 (griz), C3 (gri), X1 (griz), X2 (griz), X3 (riz), S1 (griz)
# Morning standards: SDSSJ0843-0000 (airmass 1.8) and C26202/HST (airmass 1.1)
# Superpowers allocated to team members (woot)

*Problems tagged as Synopsis_Problem*

# None

*Minor Problems and Irrelevant Information*
# Rasicam not working due to camera problems.

*Notes for Data Management*

# Due to clouds and high seeing, it might be worth declaring most exposures as bad.
