Title: 12/13 Owl Shift 8:00-16:00 UTC (0:00-8:00 PST).  All times in UTC.

State of H1: Unlocked

Shift Summary:  Unlocked for a variety of issues for the entire shift.  Wind still 30 mph with 40 mph gusts.  Microseism still 0.9 um/s.  Peter K. is here looking at ISS issues that started at the end of Jeff's shift.

Incoming operator: TJ

Activity log: Peter is onsite looking at ISS issues in preparation for locking during better (?) conditions.

With microseism up above 1 um/s, EQ/wind band near 1 um/s, winds 30 mph with gusts to 40 mph, and issues with the ISS, I haven't made much progress locking.  Also, the IMC has been dropping lock fairly frequently, about every 15 minutes.  I haven't been able to get INPUT_ALIGN to work while doing IA.  It stalls at LOCKING_XARM_IR.  Not sure if this is related to ISS issues or not.  I'll wait until one of these issues improves before calling for support.

Activity Log: All Times in UTC (PT)

00:00 (16:00) Take over from TJ
01:10 (17:10) Reset L4C WD saturations on HAM2, HAM3, HAM4, HAM5, & ITMX
02:57 (18:57) Lockloss – High winds (35 to over 40), elevated seismic & microseism 
03:15 (19:15) Temp alarm on CD Zone 4 heating duct – Temp @ 104.5f, will monitor
07:15 (23:15) Reset timing error on H1SUSETMY
08:00 (00:00) Travis on site
08:50 (00:50) Turn over to Travis, who is working with Peter

Title: 12/12/2015, Evening Shift 00:00 – 08:00 (16:00 – 00:00) All times in UTC (PT)

Support:  Peter King
 
Incoming Operator: Travis

Shift Detail Summary: Lockloss at 02:57 (18:57) – Probable cause high winds (40 plus at along X-Arm) and elevated seismic (0.1um/s Plus) & microseism (centered at 0.8um/s, but peaks well over 1.0). Weather conditions are expected to be stormy until 06:00 (22:00). Will try relocking.  

IFO is not relocking. Has not gone past DRMI_1F. Started to run initial alignment, however CS and Y-Arm now recording wind speeds in excess of 30mph with several gusts over 40mph. Seismic and microseism are also elevated. Put the instrument into Down until the wind lays down a bit. 

Wind is down to the lower 20 to mid teens, so going to try relocking after initial alignment. Part way through initial alignment wind piped back up to over 30 at End-Y and the high 20s elsewhere. During SRC_ALIGN ASC could not converge before being knocked back to down then restarting the SRC_ALIGN. Appears to be a little soon to try alignment and locking. Perhaps the Owl shift will have better conditions and success.  

Found IMC_MC2_Trans oscillating after aborted SMC alignment. ISS diffracted power was also oscillating. Called Peter King. Tried to get things stabilized by varying first loop, refsignal levels, etc. but without much luck. Turning over to Travis so I can get some sleep before tomorrow’s Owl shift.   

   03:15 (19:15) received high temp alert for CS Zone 4 AH duct. Temp is 104.5f. Will monitor.

   Lockloss at 02:57 (18:57) – Probable cause high winds (40 plus at along X-Arm) and elevated seismic (0.1um/s Plus) & microseism (centered at 0.8um/s, peaks well over 1.0). Weather conditions are expected to be stormy until 06:00 (22:00). Will try relocking.  

   Reset L4C WD saturations on HAM2, HAM3, HAM4, HAM5, & ITMX

State of H1: 00:00 (16:00), The IFO is in Observation mode. Power at 21.8W, range 76Mpc    

Outgoing Operator: TJ 

Quick Summary:  IFO has been in observation mode for the past one hour. Wind is between a gentle and moderate breeze (8 – 18mph), with some gusts over 25mph. The forecast is for stormy conditions until around 06:00 (22:00); with gusts up into the 20s. Seismic activity has been trending upward for the past 2 hours and is around 0.07um/s; microseism is also on the rise and is around 0.7um/s. With luck, these conditions will not affect tonight's observing.

• 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.
