*Observing Team*

_DES Observers:_ Marcelle Soares-Santos, Darren DePoy, Klaus Honscheid

_Telops:_ Mauricio Rojas, Claudio Aguillera

_Remote Support:_ German Schumacher

*Observing Plan*

# standard bias and dome flat sequence

# twilight flats

# BD+17 

# standard stars

# TCS test: tracking

# TCS test: guider 

# science:

* if *long exposures OK*:

** SN templates, if photometric and seeing < 1.2 arcsec 

** seeing tests if clear and seeing > 1.2 arcsec

** if thin clouds, minisurvey

** if clouds, decal sweeps

* if *long exposures not OK*:

** SN vvds deep field, for photoz 

# standard stars

*Accomplishments*

# zeros, dome flats (ugr)

# sky flats: ugr

# BD+17 (at airmass < 1.3)

# TCS test: tracking

# TCS test: guiding

# standard star fields: J0000-0000, J0200-0000, J0320-0000 

# SN templates: X3 (gr)

# std fields: J0320-0000, C26202/HST

*Problems*

# lost air to the mirror

# guider jump on exposure number 135679
