Observing
There is a blue box with the number 1 in it under the CRC column for H1ISIHAM3 on the O1 CDS detailed overview. I'm not certain what this means. Screenshot attached.

Relocking sequence:

Had to move both ETM and TMS for both arms to lock on green. Took a long time.
Stopped in CHECK_IR. IR not really found. Adjusted H1:ALS-C_COMM_VCO_CONTROLS_SETFREQUENCY and H1:ALS-C_DIFF_PLL_CTRL_OFFSET.
Modes look bad and flashes are low in power on LOCK_DRMI_1F
Starting initial alignment
Had to adjust ETMS to lock arms on green
Moved PR3 to slightly improve COMM beatnote
Done initial alignment
Had to adjust ETMY in Pitch to lock on green
Stopped at ENGAGE_ASC_PART3. Lowered diffracted power.
Had to rerequest READY_FOR_HANDOFF for OMC_LOCK node at DC_READOUT_TRANSITION. Got 'wrong node?' notification. Rerequested READY_FOR_HANDOFF. No change.
Put OMC_LOCK node to auto
It went back through the sequence and got to READY_FOR_HANDOFF
The ISC_LOCK guardian went on. While it was at INCREASE_POWER I put the OMC_LOCK node back to managed.
Got 'node OMC_LOCK: STOLEN (by: USER)' notifications on ISC_LOCK guardian.
Stopped at engage ISS second loop
Engaged ISS second loop by hand

Attempt to remanage OMC_LOCK node:
Put ISC_LOCK node to manual
Selected INIT for ISC_LOCK node
Got oh no it is unlocked voice, but it wasn't
Selected ENGAGE_ISS_SECOND_LOOP for ISC_LOCK node
Put ISC_LOCK node back to auto
Requested NLN for ISC_LOCK node

Made it to NLN!

Ops EVE Mid Shift Summary
Still locked and observing. No change in wind or seismic. A number of SUS ETMY saturations. These do not appear to be reflected in RF45 noise. The verbal alarms script is indicating CS temperature is low, but I don't see any alarms on the FMCS overview.

Shift Detail Summary: 08:50 (00:50) GRB alert – LHO in Observing; LLO down due to environmental issues. Ignored alarm.  12:10 (00:10) GRB (E202631) – LHO in Observing; LLO down due to FE problem. Ignored the alert.

Generally a good shift. IFO in Observing mode for ~ 12 hours. Range has been around 78Mpc. Other than cold and fog, weather is good and seismic has been stable for the entire shift. Only one ETM-Y saturations and no problems with RF45. No additional temperature related alarms in the corner or end stations.

Outgoing Operator: Patrick

Quick Summary:  IFO has been in Observing mode for the past 5 hours, except as noted in Patrick log entries. Environmental conditions – wind is a light to gentle breeze (4-12mph). Seismic activity is quiet after a couple of small earthquakes ~ 2 hours ago. Microseism is centered around 0.3 um/s.

Finishing swept sine in INJ_HARDWARE filterbank
LLO had called and said they would be down for awhile.

I'm going to finish doing a swept-sine through the INJ_HARDWARE filterbank from 5-500Hz. Previously I had only finished 500-2000Hz.

The IFO intent mode has been turned off.

This is WP#5595.

Previous swept-sine measurement was: aLog 23307

The following was done:
 * psinject turned off at 5:20 UTC
 * swept sine measurement started at 5:21 UTC
 * swept sine measurement ended at 5:48 UTC
 * psinject turned on at 5:49 UTC

I've attached a plot of the transfer function and coherence between INJ_CW and DELTAL_EXTERNAL_DQ.

WP#5955 is now complete.

Attached are results of computing a transfer function from 
H1:CAL-INJ_CW_OUT to H1:GDS-CALIB_STRAIN, using the
same method used for the higher-frequency swept sine on Nov 11.

The transfer function is generally flat and well behaved
below 500 Hz and above ~35 Hz. The feature at 167 Hz
appears to be an artifact of the swept sine measurement
at that point being artificially split into several points. 

Figure 1 - Spectogram of H1:CAL-INJ_CW_OUT during swept sine
Figure 2 - Spectogram of H1:GDS-CALIB_STRAIN during swept sine
Figure 3 - Transfer function and coherence

More detailed results can be found here.
