H1 Lockloss, No Observable Culprit So Far

H1 drops lock 24hrs after lockloss during Travis OWL shift last night.  Nothing obvious on our wall monitors (Striptools normal, SEIS BLRMS quiet).

HAM6 ISI tripped, and I forgot to untrip the WD, so I paused the ISC_LOCK at DRMI ON POP to get HAM6 ISI back to ISOLATED.

Yesterday we had a lockloss at just before 1am PST local time & tonight we had a locklos just after 1:37amPST local time.  Hmmmm...

EX Vacuum Gauge Still Off (i.e. PT524)

Starting my shift, one check we do is the Alarm Handlers.  The Vacuum one has an alarm for the EX PT524 vacuum gauge.  Chandra noted this went down on Tues (Fire Dept Glitch?) & looks like it's remained down ever since.  Since other gauges look good with pressures of 1e-9Torr at EX, I'll assume we do not need to pay any mind to this alarm for the moment.

These cold cathode gauges sometimes take a while to turn back on at low pressures.

Transition To OWL

TITLE: 02/20 Owl Shift: 08:00-16:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 68Mpc
OUTGOING OPERATOR: Jeff
CURRENT ENVIRONMENT:
    Wind: 5mph Gusts, 4mph 5min avg
    Primary useism: 0.03 μm/s
    Secondary useism: 0.29 μm/s

Nice and warm out and no fog to worry about.  useism looks like it's been increasing a little over the last 6hrs.
QUICK SUMMARY:

As Jeff was handing off, saw no issues, except a 5.4 Peruvian EQ popped up (followed by a 4.9 New Zealand EQ) on USGS webpage---Terramon webpage apears to be down.  Will monitor these.

Jeff mentioned an A2L would be useful to run if the opportunity arises.

Fundamental violin modes are down near 3e-19.

Have noticed that the H1 & L1 Summary Pages have been down for the last ~12hrs.

Ops Evening Shift Summary
Ops Shift Log: 02/19/2017, Evening Shift 00:00 – 08:00 (16:00 - 00:00) Time - UTC (PT)
State of H1: Locked at NLN, with 64.9 Mpc of range.  
Intent Bit: Observing
Support: N/A
Incoming Operator: Corey

Shift Summary: A2L DTT script shows pitch elevated between 20 and 25 Hz. Will run the A2L script if LLO drops out of lock.

Mostly a smooth shift. Have been Observing for the past 22.5 hours. With the exception of A2L pitch, the interferometer has been humming along all shift. There was a GRB alert, which LLO received but LHO did not. As both sites were in observing, observed the one hour stand down. Environmental and seismic conditions remain favorable.    

Activity Log: Time - UTC (PT)
00:00 (16:00) Take over from Jim
00:20 (16:20) Run A2L – Pitch is high
06:35 (22:35) GRB Alert – Reported by LLO - LHO did not receive notice
06:35 (22:35) One hour stand down for GRB alert
07:35 (23:35) End GRB alert stand down
08:00 (00:00) Turn over to Corey

Fire system panel alarming

At 11:34 UTC, I heard a sustained alarm tone near the door of the control room.  I tracked it down to the fire system panel in the Computer User's Room.  Other than the tone, I noticed that the "System Trouble" light was blinking.  I'll call Bubba when it get closer to normal waking hours.

Seems to have fixed itself as it is no longer alarming. 

travis.sadecki@LIGO.ORG - 07:39, Sunday 19 February 2017 (34243)

The alarm stopped for an hour or so, but has since started again.  I'll call Bubba now.

A bit of tweaking BS and PRM to get DRMI to lock, but otherwise no issues.
