ENR CTIO Blanco 4-m 2015-08-23

Date: 
Sunday, August 23, 2015
Telescope: 
CTIO Blanco 4-m
Submitter: 
Michael Baumer
Submitter Email: 
mbaumer@stanford.edu
Observer Support: 
Claudio Aguilera
Night Assistant: 
None
Also Present: 
Anna Schooneveld
Problems: 

SISPI failed at 12:24 local time. Restarting PANG and confiiguring several times apparently solved problem.

Several short-lived SISPI lags at 7:04 and 7:10, usual ~5min lag at 7:19

*Observing Plan*

# Community observer first half: A. Zenteno
# Mid-night standards
# Turn on ObsTac
# if clear, morning standards (while watching SISPI closely!)
# if clouded out, run obstac until 07:19 to avoid morning troubles...

*Conditions*

# Clear, winds at ~20mph  at handoff. Humidity ~30%.
# DIMM shows seeing of 0.8" at handoff, so should be decent night!

*Accomplishments*

# mid-night and morning standards
# main survey hexes all (half-)night at <1" seeing, many at 0.9" or better!
# SN-S1 grizz
# after morning standards, ran defocus_nightly in our good seeing.

*Narrative*

# Community observers had a SISPI failure at 12:24; 15min to recover (see eLog)
# Clear all night (modulo some speckle in rasicam), but windy (15-25 mph).
# Subarcsecond seeing at beginning of night; obstac took main survey hexes in izY.
# Earthquake aftershock during exposure 466750 (see cool pics in eLog!)
# obstac added g and r, seeing <1" in g band; .9" or better in rizY!
# SISPI slowdown at 7:04 this time, recovered on its own in ~2min, slowed down again at 7:10, also recovered quickly. Lagged again at 7:19 in usual fashion until end.
# Standards at midnight and twilight. Also ran defocus_nightly
