TITLE: 03/29 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ed (Cheryl covering)
SHIFT SUMMARY: Not a very good night for science. Two short locks after the earthquake rang down, both broke to unknown causes. There were SDF diffs that came and went between these two (see mid shift summary). The third lock had a steep drop in range (see mid shift summary) and also broke due to an unknown cause. Another earthquake has just hit. The ISI config has been on WINDY_NO_BRSY all night (BRSY is rung up), except for a short attempt on WINDY. Kiwamu has begun commissioning.
LOG:

07:30 UTC Restarted DTT session on nuc4.
08:42 UTC Restarted RF45 DTT session on nuc5.
08:47 UTC NLN
08:49 UTC Restarted range integrand DMT session on video0.
08:53 UTC Accepted SDF differences (where did these come from?)
08:55 UTC LLO still down. Running a2l.
08:59 UTC a2l done.
09:01 UTC Observing.
09:04 UTC Lock loss.
09:18 UTC GRB
09:39 UTC NLN. SDF differences are back!
09:44 UTC Damped PI mode 28 by changing sign of gain.
09:47 UTC Accepted SDF differences. Observing.
10:05 UTC Lost lock damping PI mode 27, but it was no where near saturating...
10:41 UTC NLN. No SDF differences this time?!
10:56 UTC Damped PI mode 28. Notice large peak around 10 Hz.
11:10 UTC Range dropping. Peak around PCAL line at ~35 Hz has broadened.
12:13 UTC Changed sign of gain to damp PI mode 28.
13:56 UTC Lock loss. PSL noise eater oscillating.
14:02 UTC Peter to LVEA to toggle PSL noise eater.
14:07 UTC Switched ISI config from WINDY_NO_BRSY to WINDY.
14:09 UTC Bubba and Apollo to mid Y
14:10 UTC Powercycled video5
14:12 UTC Set ISI config back to WINDY_NO_BRSY.

Bubba reports that the balers started on X arm at 15:00 UTC, halfway between mid and end stations, moving towards mid station.

15:27 UTC Lockloss. Earthquake.
15:35 UTC Karen and Christina to mid stations.
