SHIFT SUMMARY: Besides the one time that TCSX unlocking pushed us out of Observing(72653), we were Observing the entire time and have now been Locked for 20hrs 25mins, and it was a very quiet shift. The winds were sometimes getting up to over 30mph over the course of my shift, but have now lowered to just over 20mph.

Between 09/04 00:48 and 00:50UTC the TCSX CO2 laser lost lock and pushed us out of Observing(attachment1). There were two SDF diffs for TCS-ITMX_CO2_CHILLER_SERVO_GAIN and TCS-ITMX_CO2_PZT_SERVO_GAIN(attachment2), both of which resolved themselves as the laser locked back up. Currently these unlocks are happening every ~2.8ish days. Jeff and Camilla noted(72627) that the ITMX TCS laser head power has been declining over the course of the past 1.5 months, and the drops in the power output line up with every time that the TCSX laser loses lock(attachment3).

SHIFT SUMMARY: We have now been Locked for 4hrs 50mins. There were two locklosses from NLN during my shift, but both times locking back up was fast and hands-off. I could not find a cause for either of them.

The code changes made earlier today(72636) for mode24 seem to be working well, and there was only one time (that I saw at least) where the phase was cycled through fully, and mode24 didn't get above ~15.

Just before posting this, I heard the building creak and the wind speed at all buildings jumped up really high!

23:00UTC Detector in Observing and Locked for 1 hour

SHIFT SUMMARY:
LOG:

Stand Down request went away.
16:00-Ish UTC  PI 24 was ringing up again, and it had rung its self up 3 times. on the 4th time
I changed H1:SUS-PI_PROC_COMPUTE_MODE24_PLL_PHASE to a value that would work WITHOUT changing the state of the PI Guardian which allowed me to stay in OBSERVING the entire time.

PI Guardian Needs to be reloaded After Naoki's Changes.
Lockloss 20:45 UTC
PI Guardian was reloaded.
Initial Alignment Not run before locking. But this lock did go through Check Mich fringes.
Observing Reached @ 22:09

Ground Motion, wind, and PI's can be ruled out. But otherwise unknown Lockloss.

I just happend to see the PI's ring up this morning durning my shift and started to trend them back to see just how high PI 24 can go with out us losing lock. While just goofing off I discovered that just last night, literally the last lockloss, PI 24 had run up from 20 to 2213.5 and caused a lockloss in under 12 minutes. screenshot included. The cursor T1 cursor is set at the point were PI 24 reaches 20. T2 cursor is set to GPS Time 1377686651 which is the Lockloss timestamp.
