_Telops:_ Claudio Aguilera

*Observing Plan*

# Community observer first half: T. Abbott: superluminous SNe
# Mid-night standards (only 2)
# Turn on ObsTac
# Morning standards (while watching SISPI closely!)

*Conditions*

# Clear sky all night, except for final 20 minutes. 
# Seeing was >~ 1.5 throughout night, >~ 1.6 for the DES part (second half) 

*Accomplishments*

# mid-night standards
# main survey hexes gr
# SN-E1 grizz
# SN-E2 grizz
# SN-X1 grizz
# SN-C2 grizz
# SN-S2 grizz

*Narrative*

# Clear largest part of the night. Clouds moved in at 6:50 local time. 
# Light to moderate winds (5-30 mph). Windscreen was initially down, but was put up when winds speeds reached 10 mph. Louvers were closed when winds reached 15-25 mph.  
# until 02:34 local obstac took all supernova fields within 1.4 airmass (i.e. E1 and E2) 
# obstac then reverted to g-band main survey hexes
# at 03:18 local obstac started to observe X1, C2, S2  supernova field when they came within 1.4 airmass
# main survey hexes recommenced at 04:28 when SN survey fields were completed. 
# 2 Standards at midnight, no morning standards due to clouds. 
# Continuing morning SISPI issues starting at 7:22am, as unfortunately is usual.
