TITLE: 04/16 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Commissioning
INCOMING OPERATOR: Oli
SHIFT SUMMARY:
IFO is in NLN and COMISSONING - the squeezer is having lock issues and a team of comissioners, fellows and other staff are in the control room and working on fixing it.
19:29 UTC: Began Locking (No initial alignment)
20:15 UTC: Began Initial Alignment (after 3 IR_COMM based locklosses)
IR COMM Weirdness:
Once we started locking, ALS locked fine but IR_COMM was not found, prompting a troubleshoot of this part. There was extremely noise behavior in the relevant channel (H1:LSC-TR_X_NORM_INMON) where the usually normalized (to 1) values were showing up bizarrely high. (Screenshot 1). After initial alignment, this issue was resolved.
20:36 UTC: Initial Alignment Complete
21:21 UTC: Reached NLN
21:24 UTC: H1 is OBSERVING
21:36 UTC: Dropped out of observing due to squeezer lockloss - a team of commissioners are on the case.
22:55 UTC: Trying to get into OBSERVING without squeezing while we troubleshoot the squeezer.
