Ops Shift Summary
TITLE: 09/08 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Commissioning
INCOMING OPERATOR: None
SHIFT SUMMARY: Peter realigned the reference cavity. Dave restarted daqd to address an nds issue. TVo took charge measurements. Cheryl, Ed and Gerardo completed WP 7144. Cheryl helped me diagnose the alignment of the ALS Y arm (kept losing lock after engaging the WFS). Sheila and TVo have just brought the IFO to NLN.
LOG:

Peter realigned the reference cavity before the start of my shift.

Came in to aftershock of 8.1 mag. earthquake in Mexico.

15:07 UTC Peter out of optics lab (in before start of shift).
15:11 UTC Jeff B. to LVEA to take particle count measurements.

All of the DTT FOMS have stopped. Seems there is a nds1 issue.

15:21 UTC Changed MC2 from misaligned to aligned and then something set it back to misaligned. Turns out it was because the HAMs were in the DAMPED state instead of the ISOLATED state.

15:25 UTC Jeff B. back.

Hit Init for ISC_LOCK guardian.

15:27 UTC Set ISI config to WINDY, then back to LARGE_EQ_NOBRSXY.
15:35 UTC Jim bringing chambers from DAMPED to ISOLATED.

Jim changed ISI config to WINDY.

TVo working on charge measurements. Cheryl trending channels for WP 7124.

Dave restarted daqd to address nds issue.

16:37 UTC Cheryl to optics lab to get IR viewer.
16:43 UTC Hugh to LVEA to look for equipment.

Cheryl created new work permit 7144 to replace 7124 (may need to remove lexan cover). Approved remotely by John.

17:04 UTC Cheryl transitioning LVEA to laser hazard.
17:15 UTC Hugh back.
17:16 UTC Filiberto taking equipment into squeezer bay.
17:17 UTC LVEA is laser hazard. Cheryl, Ed and Gerardo starting WP 7144 (viewport on HAM2).

17:48 UTC Richard done.
17:58 UTC TVo done charge measurement.
17:59 UTC TVo to LVEA to look for viewport covers.
18:19 UTC Filiberto back.

18:24 UTC Ed back.
18:30 UTC LVEA is laser safe.
18:39 UTC Starting initial alignment.
18:46 UTC Betsy, Bubba, Gerardo to LVEA.
19:14 UTC Betsy, Bubba and Gerardo back.
19:43 UTC Set ISI config to SC_OFF_NOBRSXY. Jim to biergarten to lock compact BRS in prep for move.
20:38 UTC Jim done. Setting ISI config back to WINDY.
22:43 UTC Dick to CER to retrieve equipment.
