Shift Summary
TITLE: 08/01 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 53Mpc
INCOMING OPERATOR: Cheryl
SHIFT SUMMARY: Mostly quiet
LOG:
0:10 NLN, with violin mode damping left off, per Sheila's log
0:50 IFO went to commissioning for no reason I could find. IFO guardian only showed some spm diffs on SEI ETMX(that had been there all along), but there were no SDF diffs. No one had touched anything.
Guardian DIAG_SDF suggests a difference showed up momentarily on SUSITMX
From DIAG_SDF log file:
2017-08-01T00:50:00.82615 DIAG_SDF [RUN_TESTS.run] USERMSG 0: DIFFS: susitmx: 1
Dataviewer second trend show the difference was only in effect for 3 seconds (00:50:02 - 00:50:04). Conlog did not report any settings changes at this time.
susitmx just threw us out of observe again at 0:08 UTC . DIAG_SDF logs one sdf diff, but I didn't catch it. susitmx guardian log shows nothing.
I'm running a python script on zotws6 which will print the name of the first channel in the difference list if the number of SUSITMX SDF diffs becomes non-zero.
