Over the last few days there have been strange glitch patterns that appear to be harmonics of some sort showing up on the summary pages.  I've included a few plots showing this from today and yesterday.  It's not particularly easy to read off the glitch frequencies sometimes from these plots so I analyzed spectra to try and find the actual frequencies of these glitches.  The numbers below came from looking at peaks in a Strain ASD plot.  These are estimates, and for a few of them it's hard to tell exactly which peak corresponds to the glitches.

Frequencies [Hz]:

46.1    56.8    70.1    80    113.75    144    (170.5 or 176)    208    256    (302.2 or 303.2)

03:20UTC - Not a test. Confirmed alarm with Tom Evans at Livingston. Jeff is going to be leaving the 4501.3Hz PCal line running. He says that it won't hinder data regarding this alert due to the frequency range difference. He has advised that Livingston maintain their's as well to achieve 6 hrs of data necessary to complete the test.

Though there is no active alarm, HVE-MY:CP3_LT200 is in alarm state. I didn't notice th alarm handler reporting this on my last shift despit the ongoing CP3 woes. Maybe it was?

at 00:39UTC i noticed that OMC REFL and TRANS cameras are producing NO images. Also, Refl centroid is at 0:0 and Trans is off scale -1 : -1.

TITLE: Jan 10 EVE Shift 00:00-08:00UTC (16:00-00:00 PDT), all times posted in UTC

STATE Of H1: Observing

OUTGOING OPERATOR: Corey

QUICK SUMMARY: IFO locked and Observing; Wind Calm: µSei trending below 90%ile;EQ bands nominal. A little funny business with periscope resonances and SRx bounce/roll eating at the range a little bit. Dr Kissel on site doing some work. Everything is good at this point.

STATE of H1:  

Incoming Operator:  Ed

Support:   Hugh (phone)

Quick Summary:

Other than the short lock at the beginning of the the shift; got back up fairly quick & have had it in Observing for 6+ hrs (Kissel would like 12hrs with the PCal lines where they are).

Shift Activities:

• 16:49 - 17:35 Lockloss...possibly due to IMC-F_out diverging (which gave the Tidal error messages?)
• 17:37 Back To Observing
• 17:43 video3 (PSL videos) web browsers reloaded because all cameras were frozen (noticed per Ops Checksheet)
• Handing off to Ed.

Not much to pass along here.  Current lock is 5+hrs.  The range has been showing a slight trend downward as of late (i.e. from 80.5 down to 77.5Mpc).  Not seeing a reason for the drop (LSC POP A looks flat, and useism looks like it's actually dropping).

What a difference a lock makes.  

After 54min, H1 dropped out of lock this morning.  That lock had the TIdal DIAG_MAIN error messages noted earlier (but Tidal looked fine according to Hugh, whom I had on the phone).  The one issue noted was H1:IMC-F_OUT16 diverging.  

Since there were no obvious environmental/seismic reasons for the lockloss, I am blaming the IMC drift here.  And with that, I am submitting my very first FRS Report (FRS#4199) with 0.8hrs Observation Time Lost.

NOTE:  Terramon forecasts a 4.9 EQ from Turkey arriving here in about 20min (18:28UTC/10:28amPST), with motion of a YELLOW 0.15um/s....we'll see how we ride through it.

During the last lock segment, we had the Tidal Error messages (X& Y COMM CTRL within 10% of limit).  Additionally, noticed on the Striptool on nuc1 that IMC-F_OUT16 was diverging & drifting off-screen (see attached).  Ultimately there was a lockloss (could it be related?).  

Talked to Hugh while we were locked, and he pointed me to the End Station HEPIs & also to the ISC signals they get.  He mentioned they have a limit of 700,000counts.  ETMy was moving below -36,000 (this was OK).  EX was flatlined at 14,660 (this was ODD).  But since both of these were well away from 700,000, we ruled out this being a tidal issue and figured it was something upstream (ISC?  PSL?).  We'll see how the next lock looks.

STATE Of H1: Observing (at the last minute)
SHIFT SUMMARY: Changed end X PCAL freq. Lost lock coincident with jump in earthquake band. Ran an initial alignment after seeing no flashes in DRMI. All the digital cameras froze for ~ 5 min. Had issues with OMC SUS (see previous alog). Engaged ISS second loop by hand. Getting diagnostic messages for X and Y tidal limits (see attached). A trend of the TIDAL_CTRL channels for the last 30 days does not show anything unusual (see attached).

STATE of H1:   Recently taken to OBSERVING by Patrick

Outgoing Operator:  Patrick

Quick Summary:

Foggy morning on the site.  Patrick restored H1 to Observing after the EQ (from 5.0 Antartica?).  No winds and high useism (LVEA ~0.5um/s.

Have X & Y COMM CTRL within 10% of limit messages on DIAG_MAIN.

I'm stuck at DC readout transition with a message saying the OMC is not ready. I have tried rerequesting the OMC guardian state and changing the starting PZT voltage in omcparams.py.

Something strange is going on. The SUS OMC WD is tripping and untripping itself. On the OMC SUS overview screen the IOP DACKILL is oscillating between red and green, but the numbers continue to go to the DAC regardless. LF and RT are stuck railed at -131060. ... Now it has stopped and LF and RT are no longer railed.

Coincident with jump in earthquake band (see attached).

Have remained locked. Took out of observing briefly to change the end X PCAL frequency. H1:LSC-POP_A_LF_OUTPUT has been slowly falling and is now around 15,750. There is a slight indication that it may be leveling out (see attached), so I'll give it some more time to see.

Per Rick's request I changed the end X PCAL frequency from 3501.3 to 4501.3. I also changed the sine amplitude from 35,000 to 40,000. I went out of observing from 12:00:23 - 12:11:29 UTC to do this. I accepted the SDF differences from doing this (see attached). Per Rick's schedule this should be left to run for 12 hours.
