STATE Of H1: Observing 80Mpc

OUTGOING OPERATOR: Cheryl

QUICK SUMMARY: IFO is locked at NLN and Observing @ 80 Mpc. Seismic environment has quieted down from an earthquake ≈1.5 ago(rode it out quite well). Wind is quiet. Looking good to me. It also appears that NO hardware injectins are running at this time and CAL lines are ON.

LHO's fourth-Friday public tour occurred on the afternoon of 11/27.  Arrival time at LSB = 3:00 - 4:00 PM.  Departure time = 4:45 - 5:15 PM.  Group size = ~30 adults & kids.  Vehicles at the LSB = ~12 passenger cars.  The group was on the overpass near 4:00 PM and in the control room from about 4:00 to 4:40.

Timing error on H1SUSETMY. Cleared with DIAG reset.
Testpoint open on H1LSC.
Tour in control room.

Earthquake has subsided.

ISI blends are on Quite_90.

STATE Of H1: Trying to lock DRMI
SHIFT SUMMARY: Lost lock for unknown reason. Trouble relocking. Started initial alignment. Earthquake hit. Finished initial alignment. Trying to lock DRMI.
INCOMING OPERATOR: Cheryl
ACTIVITY LOG:

Lock loss
Got 'Align SR3 to offload M2 actuators' notification from SR3_CAGE_SERVO guardian.
M2 Test around 12000 in Pitch. Moved optic align in Pitch from 555.4 to 558.4 to bring M2 Test to around -5900.

Trouble locking ALS. Had to move TMSY mostly in PITCH.
Trouble locking X arm on green.
Cleared end X WFS history.
WFS seem to drive power down.
Went to LOCKED_NO_SLOW_NO_WFS.
Took ALS_XARM guardian to Auto.
Went to LOCKED_NO_SLOW_NO_WFS.
Using ETMX and TSMX was able to bring power in X arm to around .9.
Went to LOCKED_SLOW_W_ETM_WFS, lock loss, power in both arms dropped.
Took ISC_LOCK to INIT.
Moved ETMY in YAW.
Moved ETMX in PITCH.
Moved TMSX some, but didn't help.
Power in X arm is around .9. Power in Y arm is around 1.06. Going to CHECK_IR.

ALS-COMM guardian: brief 'alignment is bad not searching' notification, finally 'search for IR resonance by hand'.
ALS DIFF guardian: request and state is still on LOCKED. Something isn't right.

Starting initial alignment. May be faster in the long run.
ALS_X and ALS_Y have both reached INITIAL_ALIGNMENT state, but X arm power is oscillating around .8.
Let ASC loops converge for ~ 30 min. The ITMS were far off.
Offloaded green WFS.
COMM beatnote is oscillating < 2.
Noticed earthquake.

Waited long time for earthquake, it isn't completely settled, but will try moving on
Aligning PR3 to increase COMM beatnote
That worked very well, increased to almost 5
MICH_DARK_LOCKED did not work, the two beams oscillated further and further away from each other
Going back to input align
Input align is not locking
Trying MICH dark locked again
This time the beams converged
SRCY is not locking
Got H1:LSC-ASAIR_A_LF_OUTPUT to ~ 800 by moving SRM mostly in YAW
Finished initial alignment

Moved ETMY in PITCH and YAW to lock ALS
ALS DIFF: search for IR resonance by hand
Briefly locked DRMI, lost lock, went to down
ALS DIFF: search for IR resonance by hand
Back to trying to lock DRMI

• In general, the features seen during this DQ shift were already known. The IFO behaved as it had in previous days with no unusual issues. The average duty cycle (including the maintenance time) was 61% with some locklosses and difficulty in relocking at various times attributable to earthquakes, high winds, and high microseism.
• Lines at about 500 Hz and 2400 Hz (violin modes and butterfly mode respectively) were seen at the beginning of most locks. A line at about 300 Hz was seen on spectrograms with a narrowed (50 Hz to 600 Hz) frequency range.
• The 650 Hz wandering line (see alog) was present in locks 1, 2, and 4 on 23 Nov, absent in lock 3 on 23 Nov and during the lock on 24 Nov. It returned in the lock on 24 Nov at a higher frequency of about 670 Hz.
• Hveto results were available on 23 Nov and 24 Nov. The channel H1:ASC-X_TR_B_NSUM_OUT_DQ (second round winner on the 23rd and 4th round winner on the 24th) picked up ETMY saturations. Links to the Omega-scans for the loudest events in this class are provided in the complete report. The dominant (1st round winner) channel every day was H1:ASC-MICH_P_OUT_DQ. This channel picked up glitches located at around 5 Hz and unlikely to affect the searches.
• Nothing interesting was found in BNS and BBH loudest events.
• An excess noise of unknown origin was observed at around 70 Hz. It was strong on 25 Nov but could be seen at various intensitites in the narrowed (50 Hz to 600 Hz) frequency spectrograms back to 5 Nov when that plot first appeared in the Summaray Pages.

The 0.03 - 0.1 Hz (earthquake) seismic band is between ~ 0.01 and 0.04 um/s.
The 0.1 - 0.3 Hz (microseism) seismic band is between ~ 0.1 and 0.4 um/s.

The winds are between ~ 0 and 5 mph.

The ISI blends are on Quite_90.

From pinging:
CDS WAP is off at the LVEA.
CDS WAP is on at mid X.

STATE Of H1: Observing

SUPPORT: N/A

LOCK DURATION: 8hrs

INCOMING OPERATOR: Patrick

SHIFT SUMMARY: Locked at 80Mpc+. A few ETMY glitches. 45MhzRFAM is nice and normal. Winds are still calm. Seismic activity is relatively quiet. Handing off to Patrick.

I have incremented the heat at XEND. The HC3 control signal has been increased from 13.5 to 14.5 ma.

Outside temperatures shown in plot.

MID-SHIFT SUMMARY: Locked at 80Mpc+. A few ETMY glitches. 45MhzRFAM is nice and normal. Winds are still calm. We rode out an earthquake from the Burma are and are currently facing a possible 1µm/s wave from an El Salvadoran quake. THere was an FMCS alarm that I logged and sent an e-mail to Bubba about. It looks as if there was a change made to the temp in the CS yesterday at some point around 12:00UTC and the alarm threshold for this is set rather tightly. Livingston remains down since 09:46UTC.

Critical Alarm at 11:15 for H0:FMC-CS_LVEA_REHEAT_2B_DEGF. Attached trend show past 24 hours for this channel. I'm not entirely sure how long this alarm has been present. Also attached is a screenshot of the current CS FMCS. I noticed the aLog regarding the temp increase at Y end . I have not yet found one regarding the corner station.
