Both EY and EX now have Laptop charging stations in the garb rooms which contains 2 CDS laptops. These Laptops are actively being charged while they are plugged into the charging station.
Note: these laptops will not let you login if the wifi is turned off at the End station so be sure to let the opperator know that you need wifi at the end station.
The Laptops at EX are:
cdsdell425
cdsdell437
The laptops are EY are :
cdsdell431
cdsdell285
Lockloss @ 23:10, looks like DARM IN1 LSC saw the motion first - cause unknown.
I swept the LVEA after maintenance activities completed. Everything was nominal except for the CER lights were left on.
As part of maintenance I updated the x509 certificate for lhocds, it is good for another year.
H1 is still down for maintanence work, but should begin relocking in the next 15 minutes.
Dust monitors running smoothly.

Travis confirmed a good fill curbside.
Jonathan, Erik, Dave:
Erik is replacing the failed h1hwsmsr (ITMX) V1 computer with a spare unit this morning. I have stopped the temporary HWS-ITMX IOC (started on cdsioc0 yesterday) to prevent duplication of EPICS channels. This is the cause of the EDC and SDF disconnect channel counts.
TITLE: 01/02 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
OUTGOING OPERATOR: Tony
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 2mph Gusts, 1mph 5min avg
Primary useism: 0.03 μm/s
Secondary useism: 0.28 μm/s
QUICK SUMMARY:
- H1 down for maintanence day, looks like a relatively light day today
- CDS/SEI/DMs ok
Workstations were updated and rebooted. This was an OS update. Conda packages were not updated.

STATE of H1: Corrective Maintenance
INCOMING OPERATOR: Tony
SHIFT SUMMARY: We lost lock once during the shift from the HAM3 ISI watchdog tripping from the CPS sensor. It then kept tripping the ISI so we're holding in down with the IMC offline and HAM3 in damped until the problem can be addressed in the morning during maintenance.
02:20 Lockloss alog75114
03:20 Back into observing, pretty quick automated relock
06:19 lockloss alog75119
06:24 the HAM3 ISI tripped from a CPS glitch it seems? Then 10 minutes later it tripped with a larger glitch at 06:34
DIAG_MAIN reports
Lockloss
We've been locked just under an hour
We lost lock at 02:20UTC, relocking was straightforward, back to NLN at 03:14 in observing at 03:20.
Lockloss at 02:20UTC, HAM3 ISI watchdog trip from the cps sensors? Seismic motion was increasing at the time. CPS_H2 sees a big spike which presumably was the trip.
Back into observing at 03:20UTC
This looks like a CPS glitch, H2 and V2 sensor see coincident spikes not seen on other sensors. I think these sensors are both in their own box, corner 1 and 3 are in the other chassis, I will take a look during maintenance tomorrow.

SHIFT SUMMARY: Mostly quiet shift with just one lockloss with an unknown cause. H1 has now been locked and observing for 4.5 hours and the ITMX HWS camera is still stuck ON (alog75106).
LOG:
Lockloss @ 18:23 UTC - no obvious cause.
LSC-DARM showed the first motion, as usual for these types of locklosses.
Back to observing at 19:31 UTC
