• TITLE: 12/12 Day Shift: 16:00-00:00UTC (08:00-16:00 PDT), all times posted in UTC

• STATE Of H1: Observing at 70Mpc for 2hrs

• SUPPORT: Robert, Jordan

• SHIFT SUMMARY: One mysterious lockloss and the other paired with a low frequency noise in DARM. We are up and locked again but the noise hasn't dissapeared. The wind has also just raised above 20mph.

• INCOMING OPERATOR: Jeff B

• ACTIVITY LOG:

• 17:20 Robert to LVEA for PEM inj
• 17:59 Robert out, back to Observing
• 18:09 lockloss
• 18:11 Robert to LVEA
• 19:16 Robert out
• 20:52 Observing
• 21:32 Lockloss
• 22:43 Robert to LVEA inj
• 23:01 Robert out

A simple in and out for 15min, but the low frequency noise in DARM is still affecting us.

There is still some noise seen in DARM <70Hz, but not as bad as before. I am also not seeing the oscillations like before, or at least not yet. Something is not healthy though...

Range: 71Mpc

H1:LSC-POP_A_LF_OUTPUT started to get a few hz oscillation in it, and the noise in the DARM spectrum < 100Hz picked up a bit.

Had to run through an initial alignment, and then lost it a few times on the way up. The wind is still staying below 20mph, the useism is still trending down, CW inj running, lights are off, LLO is down.

I was having issue keeping the IMC locked, I looked at the PLS status and the chiller alarm was red. I went in to check it out and the bottom of the chiller was in error with "Low Level", the top seemed to be hovering around the Max line. I am not sure if the bottom is seperate from the top, but I added 200mL of water to the bottom. Alarms all good now.

Not sure of the cause yet, the control signals didn't show any signs of struggle, winds <20mph, useism 0.8um/s.

LLO is down due to high wind, Robert is jumping on this opportunity to do some PEM injections.

Title: 12/12 Owl Shift 8:00-16:00 UTC (0:00-8:00 PST).  All times in UTC.

State of H1: Observing

Shift Summary: Locked for my entire shift, 12+ hours total.  A handful of ETMy saturations.  Microseism is slowly coming down, currently ~0.6 um/s.  Wind is picking up a bit to ~15 mph.  There is a H1SUSETMX timing error on the CDS overview screen that can be cleared next time we are out of Observing.

Incoming operator: TJ

Activity log: None

Locked in Observing for ~9 hours.  A couple of ETMy saturations.  No other issues.

I noticed a couple of errors that showed up in the VerbalAlarms window running on the Alarm Handler computer.  These were not announced verbally by VerbalAlarms.  See attached screenshot.
