• 16:24 UTC Observing
  • 16:32 - 16:35 UTC We dropped Observing as the H1:CAL-INJ_CW_OUTPUT was not outputting anything, it restarted on its own after a few minutes? I toggled the master switch off and back on but I don't think that did anything.
  • 19:05 UTC lockloss right before the calibration measurement (I had asked LLO if we could delay from 18:30 to 19:15)
• 20:27 UTC Observing
  • 20:51 UTC lockloss

• 21:56 UTC Observing

20:51 UTC lockloss

19:05 UTC lockloss while we were in the last 15 minutes of thermalizing before the calibration measurement.

QUICK SUMMARY:

  • Marc is finding a spare to swap in
  • We were locked for just over 25hours when the card failed
• Wind has been moderate overnight, but we rode through all of it
• Secondary microseism is starting to creep up a little

August 5th Randy and I removed two braces from the BSC work platform at EY. These were used to stabalize the work platform by connecting it to the flange around the BSC chamber. These had been in place since the platform was originally put in place. These were the only two still in place.

Lockloss @ 04:45 UTC after 18+ hours locked - link to lockloss tool

Perhaps caused by the smallest of ETMX glitches starting in L3 right before the lockloss? Doesn't exactly look to me like a usual one of these, though. Otherwise, no obvious cause.

Jumping right into an alignment given the long lock stretch.

SHIFT SUMMARY: Observing at 151 Mpc and have been Locked for over 9 hours. Nothing really happened today besides the calibration commissioning from earlier.

We don't think it affected anything, but at 20:48 UTC, we had a staff member in a car drive up to the LVEA receiving door, idle there for 5 minutes, and then drive away at 20:53UTC, so I'm tagging detchar in case we see anything weird in the data during that time.

SHIFT SUMMARY: Currently Observing at 145 Mpc and have been Locked for 50 minutes. Relocking went pretty well today with the only concern being the fast shutter not firing during the last lockloss (86324), but luckily it seems like we were okay and that was expected in that situation.
