*Observing Team*
_DES Observers:_ Ross Cawthon, David James
_Telops:_ Manuel Hernandez, Claudio Aguilera
_Remote Support:_ ---
*Observing Plan*
# DES until 11:30 CLT, then community time, then DES starts again 4:30 CLT
# evening Standard stars
# run ObsTac queue
# morning standards
*Conditions*
# Scattered clouds and humidity around 75% to start the night.
# With humidity stabilized around 75%, dome opened at 9:34 CLT. Plan to wait 10 minutes for telescope to equilibrate temperature after not being opened at all last night. See how conditions go.
# Standards began at 10:01, ObsTac started at 10:13
# Early part of night, seeing quite bad as mirror 2 or so degrees warmer than dome. Image seeing often around 2 arcmin.
# Rest of night conditions pretty good, seeing around 1 arcmin. Clear skies.
*Accomplishments*
# Evening standards (taken late, see above), E8-A, SDSSJ2300-0000
# Satellite and aTmCam checked.
# Early night (bad seeing due to dome/telescope temperature) many g and r band widefield images
# SN-E1 done early in the night, while the seeing was bad (>1.7 arcmin on images)
# At end of night (seeing 1-1.4 arcmin): SN-E2, SN-X2, SN-X3 observed
# Morning standards SDSSJ0100-0000, SDSSJ0320-0000, SDSSJ0320-0000
# Weekly defocus/refocus script ran
*Minor Problems and Relevant Information*
# See weather delays above.
*Notes for Data Management*
# Early night images had poor seeing, including SN-E1.
