I believe I have moved IM1 and IM2 to there approximate positions before the HAM2 ISI trip (alog 23777). I moved IM1 in PITCH from 800 to 592. I moved IM2 in PITCH from 17980 to 17232.

I started an initial alignment. I got to the point where both ALS_XARM and ALS_YARM were at the INITIAL_ALIGNMENT state and was waiting for the ASC convergence. However when I got to GREEN_WFS_OFFLOADED the Y arm dropped in power. I am now struggling to bring it back.

I'm guessing related to tidal diagnostic messages.

I just noticed that the DARM spectrum is rising significantly on and off up to around 100 Hz. There are diagnostic messages related to TIDAL LIMITS (see attached screenshots). Starting investigation.

Quiet shift so far. A couple of SUS ETMY saturations. Still in observing. No significant changes in environment.

STATE of H1:  Locked for 23+hrs & range is at 80Mpc

Incoming Operator:  Patrick 

Support:  None needed.

Quick Summary:

These are the types of shifts we want!

Shift Log:

• ETMy Saturations:  16:36, 16:41, 18:30, 18:33, 20:24, 20:50
• LVEA FMCS Alarm noted & alarmed again toward end of shift.
• 0.03-0.1Hz band has been trending up for last 10hrs (since last EQ event?).  useism might be inching up a little.  Dead calm winds.

Quiet & Cold shift.  Temperatures around 21degF.  Winds are under 3mph.  useism has a slight increasing trend over last 12hrs, but the LVEA is low at around 0.275um/s.  the earthquake band is mainly flat, but has had a slow increase over the last 4hrs (no EQ notices though).

H1 range has had a trend down from 80mc to 75Mpc over the last half hour.  ETMy continues to saturate.

ASC DHARD Pit (red channel on wall) continues to have a large amplitude.

Ed mentioned a CRITICAL alarm yesterday for H0:FMC-CS_LVEA_REHEAT_2B_DEGF.  I'm seeing this not as a CRITICAL Alarm, but as an alarm for the AIRHANDLER, and it is MAJOR (i.e. RED).  Looks like it started alarming around midnight a few times (i.e. when it's been cold?).  Attached is a trend of relevant channels.  I will NOT contact Bubba/John since from Ed's alog it sounded like they are already on top of this.

O1 days 66 - 71. Quiet week, no restarts during maintenance Tuesday.

STATE of H1:  Running at 78Mpc (Lock Clock = 16:43 as of 17:22utc)

Outgoing Operator:  Ed

Support:  Evan (Fellow)

Quick Summary:  Looks like a great night for Ed even with the ETMy saturations (I've had [3] big ones in my first 85min this morning).

useism looks like it's been inching up slightly (up maybe 0.02-0.05um/s?) over the last 12hrs.  It is a balmy 19degF out!

Cheryl, Ed

Cheryl asked me to post these plots in the case that locking becomes dificult, especially in the "INPUT_ALIGN" and "FIND_IR" stages of aligning and locking. It seems that 3 days ago after a HAM2 ISI trip there was a 15µRadian shift in IM2 M1 pitch and ≈7 µRadian shift in IM1 M1 of the same. The plot also shows the compensation that IM4 has made which ultimately affects the beam pointing/alignment for the entire IFO. Should re-locking become difficult or not stable it's possible that IM1 and IM2 may need to be driven back to the values from when the shifts took place. How much shift is too much shift is still being discussed.

Please feel welcomed to correct any inaccuracies in this log as I'm relaying information from Cheryl who's knowledge of this exceeds mine, i believe.
