SDF diffs Changes were made today. I'm not sure if they were intentional or not.
But since we are in NOMINAL_LOW_NOISE I'm gonna accept them.

#edit: at 2AM when I first posted this ALOG the picture of the SDF Diffs were wrong.  I have since fixed that.
same issue with ALS-Y_REFL_SERVOIN1GAIN and ALS-Y_REFL_SERVO_COMBOOST, I just accepted the changes.

TITLE: 09/16 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 144Mpc
INCOMING OPERATOR: Tony
LOG:

• 0226 Lockloss
  • Tweaked X&Y arms by hand to speed up locking
• 0350 Back to Observing

H1 recently had a lock end after just over 8hrs.  Currently waiting for H1 to get back to NLN.  

Environmentally all is well.

STATE of H1: Observing at 147Mpc
INCOMING OPERATOR: Corey
SHIFT SUMMARY: Relocking after the lockloss (72911) was a bit strange but seemed like a one-off. Rest of the day was quiet.

15:00UTC In Observing, have been Locked for 18hours

16:38 Lockloss (72911)

16:51 LOCKLOSS_PRMI during third time going through ACQUIRE_PRMI, took itself to DOWN and restarted
17:02 I took it into INITIAL_ALIGNMENT
17:32 INITIAL_ALIGNMENT completed, heading to NOMINAL_LOW_NOISE

17:42 Lockloss at OFFLOAD_DRMI_ASC

18:24 Reached NOMINAL_LOW_NOISE
18:41 Into Observing

All looks nominal for the site HVAC fans (did catch a transition between fans at MY for this one).  Closing FAMIS 26251.

SHIFT SUMMARY:  Uneventful shift (mostly) with H1 approaching 10hrs of lock.
LOG:

• 0301-0303:  Bumped out of OBSERVING due to TCS (corrected itself).
• Had a couple of Short GRB alerts during the shift.

Bumped out of Observing due to TCSx CO2 Laser unlocking.

( 2023-09-16_03:01:35.894099Z TCS_ITMX_CO2 [LASER_UP.run] laser unlocked. jumping to find new locking point )

• Above obtained via:  "guardctrl log -a "09/16/2023 03:01 UTC" -b "09/16/2023 03:03 UTC" TCS_ITMX_CO2"

TCS_ITMX_CO2 guardian node was able to restore the laser back up within 70 sec...then I took H1 back to OBSERVING.

QUICK SUMMARY:

Got a run down of the Day from Oli (not much to report for H1 other than known investigations into EX glitches prior to locklosses).  Microseism has a slow increase over last 24hrs and winds are low.

(My first time in the Control Room for a while and it is noticeably quieter in here--- i.e. less fan noise?)

SHIFT SUMMARY: Have now been Observing and Locked for 2hours. Fairly quiet day today with only the one Lockloss

15:00UTC Detector in Observing and Locked for 16hrs 22mins

18:55 Earthquake mode activated due to earthquake from Chile
19:05 Back to calm

19:54 Lockloss

21:04 Reached Nominal Low Noise
21:19 Observing

LOG:             

The BBB channel was continually going into the alarm range.  It's been removed from Picket Fence FOM and EPICS.

The steps for removal were:

1. Edited /opt/rtcds/userapps/release/isi/h1/scripts/Picket-Fence/LHO-picket-fence.py.  Commented out the block at line 39 that adds the "BBB" channel.

2. VNC to nuc5.  Close the Picket Fecne window.

3. ssh as controls to nuc5.  Run "start/launch.sh".  This restarts the Picket Fence FOM, which also sets the EPICS variables.

Lockloss at 09/15 19:54
