FAMIS 19995
Only major event of note is the laser going down from a power glitch three days ago; everything seems to have recovered as expected.
EDIT: Forgot to attach the trends.

Jordan confirmed a good fill curbside.
The review team for the NonSENS online cleaning asked both observatories to gather 1 hour of otherwise undisturbed time with NonSENS subtraction engaged, so that they can do some tests before approving the cleaning for online use.
Since LLO is unlocked, Tony just turned on the NonSENS subtraction. This has us in Commissionining. We'll stay this way for 1 hour, or we'll go back to Observe when LLO is back, whichever comes first.
Richard asked me this morning to look at air flows at EX and to possibly turn the flow down. I have adjusted the flow from 8300 to 7000 CFM. This should not have any effect on the temperature.

SHIFT SUMMARY: We're Observing and have been Locked for 19hours. Quiet shift with the only thing happening being elevated dust in the PSL for a bit and Ryan S turning the PSL watchdogs back on. PSL ISS Diff power is still low, but can wait until tomorrow or the next lockloss.
23:00UTC Detector Observing and Locked for 11hours
01:00 Ryan S turned PSL Watchdogs on - we stayed Observing (73081)

CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 12mph Gusts, 9mph 5min avg
Primary useism: 0.02 μm/s

QUICK SUMMARY:
Taking over for Tony - we are Observing and have been Locked for 11hours. Wind has gone up just past 20mph in the last hour and useism is also trending upwards.

A newly regular ground motion has appeared in the corner station, which was first noticed in the 10-30 Hz SEI/BLRMS (figure 1) and some of the CS ACC floor sensors (figure 2, notice the short blips near 30 Hz). They appear consistently every 80 or so minutes. It's getting picked up by varous other sensors, including in SUS/OpLev/BLRMS pitch for SR3 and ITMX (figure 3) and yaw for ITMX in the same frequency range, and a PSL table microphone (figure 4).
I created spectrograms for H1:PEM-CS_ACC_LVEAFLOOR_XCRYO_Z_DQ (figure 5) and H1:GDS-CALIB_STRAIN_CLEAN (figure 6) over a 2 hour period starting Sep 22 at 8:00 UTC, which shows that this noise is somehow coupling to the strain channel, though it is fairly faint.
The feature in the SEI/BLRMS channel has appeared from time to time although not with the frequency and regularity seen now. It seems to have started around 23:00 UTC on Sep 21, but persisted through Sep 22 and 23. It's still present today (Sep 24), though its cadence has seemingly changed (figure 7).
Laser Status:
NPRO output power is 1.829W (nominal ~2W)
AMP1 output power is 67.07W (nominal ~70W)
AMP2 output power is 134.8W (nominal 135-140W)
NPRO watchdog is RED
AMP1 watchdog is RED
AMP2 watchdog is RED
PMC:
It has been locked 2 days, 4 hr 17 minutes
Reflected power = 16.19W
Transmitted power = 109.8W
PowerSum = 126.0W
FSS:
It has been locked for 0 days 7 hr and 33 min
TPD[V] = 0.8411V
ISS:
The diffracted power is around 1.8%
Last saturation event was 0 days 7 hours and 33 minutes ago
Possible Issues:
NPRO watchdog is inactive
AMP1 watchdog is inactive
AMP2 watchdog is inactive
ISS diffracted power is low
It seems I had forgotten to turn the power watchdogs back on after recovering the PSL Friday morning (this shows exactly why we have this weekly FAMIS task to check for these things). I was able to log in and turn the watchdogs on shortly after 01:00 UTC this evening. H1 did not have to drop observing for this as the power watchdogs are just Beckhoff controlled and not monitored by SDF.
The ISS diffracted power still needs adjusting; we'll wait for a lockloss to do that.

QUICK SUMMARY:
Detector has been Observing and Locked for almost 2 hours now. Winds look like they have spiked up just past 20mph in the last halfhour, and microseism is low.
The LVEA zone 5 temp looks like it peaked about an hour ago, but didn't go up as high or as sharply as yesterday's temperature peak.

This Lockloss happened while waiting for the Camera Servo Gaurdian to get to CAMERA_SERVO_ON.
