Night Assistant: 
Alberto Alvarez
Also Present: 
Claudio Bruderer, Kathy Vivas (second half)

Some SISPI issues having problems with the interlock during afternoon calibrations. Restarted it and everything was fine.

During the night recorded 2 Occlusion Alarms > 15 deg.

*Observing Plan*
 
# standard bias and dome flat sequence
# evening standard stars
# run ObsTac queue
# Standards carried out
# handover to 2nd half
 
*Conditions*
 
# weather in afternoon: 4pm (local): Cirrus spread all over, clouds on horizon
# weather after dinner: 7pm (local): Thin Cirrus everywhere.
# weather at 10 deg twilight: 21:30 (local): Clear 
# weather summary: 2am (local): 
# Seeing conditions: Median: 0.89  RMS: 0.16
# Wind conditions: none at start of the night, then increasing from the NE, 10-12 mph peak, closed louvers at UT 04:20
 
*Accomplishments*
 
# Afternoon: zeros done 276233-276243 and 276319-276327, (ugriz) dome flats done 276244-276318, checked all ok, but u was lower than expected
# Winner of post sunset leisure activity: A fox making his way into the dining room...
# Evening: Standards 276333-276347
# Survey Exposures 276350-276461
# Middle of night (end of half night): Standards 276462-276466
 
 
*Problems tagged as Synopsis_Problem*
 
None.
 
*Minor Problems and Relevant Information*
 
# Some TCSInterface issuses during afternoon calibrations, restarted everything with image 276233 and ran from there
# Occlusion alarms: 5 alarms during the night, 2 severe.
 
 
*Notes for Data Management*
 
# Image 276434 is clearly a bad image (looks like streaking) and has to be re-added to ObsTac. Image 276235 and 276235 had an Occlusion Alarm of 17 and 22 degrees respctively.
