ENR CTIO Blanco 4-m 2015-08-20

Date: 
Thursday, August 20, 2015
Telescope: 
CTIO Blanco 4-m
Submitter: 
Michael Baumer
Submitter Email: 
mbaumer@stanford.edu
Observer Support:

Night Assistant: 
None
Problems: 

Continuing problems with SISPI starting at 7:22am local time. The GUI falls behind reality (as assessed by log files) by ~5 minutes and freezes.

*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*

# Clouds early in night cleared by 23:00 local, light clouds returned around 3am local. 
# Seeing was 1.3" +/- .2" throughout night

*Accomplishments*

# A few sub-arcsecond images!
# 1 ndsflat field sequence (now have 10/10!)
# mid-night and morning standards
# main survey hexes
# SN-X3 deep z band
# SN-C3 deep g and r bands
# SN-C1 grizz

*Narrative*

# Clear at first but thin/cirrus clouds moved in around 03:00 local. Moderate winds (10-20mph).
# obstac took main survey hexes.
# obstac reverted to mainly supernova fields after 03:30 local.
# at the end of the night, obstac pointed straight up for better seeing.
# 2 Standards at midnight (clear) and twilight (cloudy). 
# Continuing morning SISPI issues starting at 7:22am, as unfortunately is usual.
