TITLE: 11/14 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Nutsinee
SHIFT SUMMARY: Have spent the majority of the shift alternating between trying to get the SRC to lock in initial alignment and trying to get DRMI to stay locked. I was able to get PRMI to lock stably, and DRMI would keep locking briefly, but only stayed locked once. When it did stay locked I tried moving around the SRM but it didn't seem to have much effect, and I don't think the signals got high enough for guardian to say the LOCK_DRMI_1F state was complete. I then noticed that guardian was complaining about a lost connection to a channel (I think it had trigger in the name), so I tried INIT to see if that would reconnect it. Unfortunately that broke the DRMI lock. I don't think the earthquakes have helped much either. Looking back in the alog, I saw Sheila's post about changing the SRCL FF. After trending back I changed the H1:LSC-SRCLFF1_SW1S and H1:LSC-SRCLFF1_SWSTAT back to what I think they were before she made the change. I don't think this has made any difference.

I restarted nuc5 and video4. Later in the shift the seismic trace on the lower screen disappeared. Yesterday it was the seismic plot on the upper screen that disappeared.

I had to restart OAF once.

The earthquakes have rung down.
LOG:

16:59 UTC Restarted nuc5 (twice) and video4. Apparently the televisions turn off and stay off when nuc5 is restarted?
17:19 UTC IMC is not locking
18:19 UTC Toggled the PSL noise eater switch. Used LLO operator for buddy system since no one else was here.
18:28 UTC Changed the ISI configuration from EARTH_QUAKE_V2 to WINDY
18:51 UTC Cleared history on all IMC WFS DOF. IMC locked immediately. Getting notifications of IMC WFS not centered.
18:59 UTC The ALS X arm is locked on green but the transmission is only around .9. I could try moving TMS but I think I should do an initial alignment.
SRC is not locking in initial alignment. Each time I take it to down to try again the SRM and HAM5 ISI trip.
20:22 UTC Giving up on SRC alignment for now. Going to skip and try to lock DRMI.
20:57 UTC I can get the PRC to lock stably. DRMI will lock briefly but not hold.
21:14 UTC Trended back SRM alignment sliders. They seemed to change substantially 5 hours or so ago. Moving them to match and retrying SRC initial alignment.
22:16 UTC OAF glitch. Restarted with script.
23:10 UTC Trying initial alignment again.
23:24 UTC SRC still won't lock
23:49 UTC Trying to see if undoing the changes I believe Sheila made to the SRCL FF will help:

This does not appear to help.
