STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Tony
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 14mph Gusts, 10mph 3min avg
    Primary useism: 0.04 μm/s
    Secondary useism: 0.09 μm/s
QUICK SUMMARY: H1 lost lock early this morning at 11:01 UTC from a non-obvious cause, then while relocking, a M6.3 EQ from the Northern Mariana Islands caused a lockloss while powering up and kept H1 down for a while. Currently have relocked up to OMC_WHITENING and have been damping violins for about 20 minutes. Commissioning planned to start at 15:30 UTC.

• Wind and microseism bands are low (despite several recent quakes)
• All other systems nominal

STATE of H1: Observing at 152Mpc
INCOMING OPERATOR: Tony
SHIFT SUMMARY: Currently observing at 156Mpc and have been locked for 1.5 hours. The huge earthquake kept us down for most of my shift, but we were finally able to get back up. The earthquake tripped almost everything, and the IMs and PR2 had become shifted so much that we weren't getting any flashes on the X or Y arms in IR during initial alignment. With Camilla's help, we were able to get INPUT_ALIGN for XARM to run by watching the driftmon trends for those optics and using the optic align channels to adjust their pointing back to where they had been before the earthquake. After that, the rest of initial alignment went by quickly and then relocking was smooth.
LOG:

23:00UTC Unlocked and waiting for ground to stop moving from lockloss-causing earthquake
00:00 Untripped suspensions(MC2, MC3, SRM, IM2, OFI, TMSX), HEPI(HAM1), and ISI(all except HAM6) that had tripped
00:36 Ground finally moving less, started an initial alignment
    - INPUT_ALIGN - no light from XARM IR
    - Tried INPUT_ALIGN for YARM - still no luck
    - We had to trend PR2 and IM1/2/3/4 driftmon and adjust OPTICALIGN to change pointing to what it was before the earthquake
02:26 initial alignment done, relocking

STATE of H1: Earthquake
INCOMING OPERATOR: Oli
SHIFT SUMMARY: Very uneventful shift until towards the end when a large earthquake knocked H1 out of lock after 15.5 hours.

• 14:30 - H1 observing for 8 hours
• 22:25 - Lockloss from large EQ in British Columbia, all ISIs and several suspensions tripped
  • See Oli's alog for details

Still waiting for ground motion to calm down before untripping things and starting alignment.

No log for this shift.

STATE of H1: Earthquake
OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
    SEI_ENV state: EARTHQUAKE
    Wind: 17mph Gusts, 11mph 3min avg
    Primary useism: 1.06 μm/s
    Secondary useism: 0.69 μm/s
QUICK SUMMARY:

Currently in DOWN and waiting for the earth to stop ringing from the earthquake (80101). We should be able to start untripping things and starting alignment hopefully within the next hour.

Lockloss @ 09/15 22:25UTC after 15.5 hours locked due to a 6.5 earthquake from off the west coast of Canada. Peakmon went above 280,000 counts, almost everything tripped, and the earthquake registered in BIG RED BUTTON on the plot. We only noticed when the University of Washington OTR picket fence trace starting increasing, but I initially thought it was a glitch because of how fast it was increasing. We'll be out for a while. Here are some fun screenshots:

SHIFT SUMMARY: Currently Observing at 155Mpc and have been Locked for over 17 hours. During this lock so far we've hit 160Mpc for the CLEAN_SNSC range channel and 166Mpc on the CAL_SNSW channel. Our squeezing isn't good at the higher frequencies, but I haven't been able to run sqz alignment because Livingston and Virgo have been staying nice and locked this entire time as well. Superevent S240915b during my shift but other than that has been a quiet evening.
