STATE of H1: Observing at 149Mpc

SHIFT SUMMARY:
One lockloss toward the middle of the shift. As well as an unlocking TCSx laser for that lock. Currently Observing (after taking two attempts to get to NLN in the latter part of the shift).
LOG:
13.5hr lock just ended with a lockloss (and also had an OBSERVING drop due to TCSx laser earlier). Currently waiting for H1 to get back up to NLN.
Identical drop from OBSERVING due to unlocked TCSx laser which happened on Sept 15 (alog #72908).
Here are the notables:

QUICK SUMMARY:
H1's been locked for just over 10hrs. (Wow--interesting to see seismis noise ever since I left last night! Lots of earthquakes around the globe which made for a rough overnight!) Quick scan of the Control Room and everything looks good right now.
Outgoing should be Austin! sorry about that.

SHIFT SUMMARY:
- 16:38 - inc 5.7 EQ from Papua New Guinea
- EX saturations @ 18:27/20:28/20:57/21:31
- Seems like H1 started reading back "No Data" on gwistat, this occurred sometime between 20:00 - 21:00 UTC, according to the gwistat bot (H1 was locked and in observing mode during this time) - Tagging DetChar
LOG:
No log for this shift.
H1 is still in observing, just reached a 6 hour lock. Other than a couple small EQs, it has been a quiet shift thus far.

tl;dr
To get the update, git pull at the picket fence folder. Also, don't forget to install cartopy so the picket map scripts work.

QUICK SUMMARY:
- H1 is locked and observing - just hit 2 hours
- Following a night of EQs, things seemed to have calmed down
- CDS ok
- Dust monitor alerts for LVEA 6 (HAM 6) and 10 (BSC1), will monitor as the day progresses
No issues with picket fence this morning. All four outbuilding weather stations stopped updating at 03:25 and were automatically restarted at 04:00.

STATE of H1: Observing at 150Mpc
INCOMING OPERATOR: Ryan C
SHIFT SUMMARY:
Quiet shift up until H1 lost lock after 30hrs. H1 took a bit of time to come back even through a Guatamalan EQ (which was not the reason for the lockloss, just an added impediment to relocking). Ultimately took H1 to Initial Alignment and after this H1 has been swiftly making it's way to NLN w/ no issues.
NOTE: Just before the end of the shift a M6.2 EQ from Afghanistan was inbound! :-/
LOG:
Smooth shift with H1 locked 28.5hrs with a range between 140-146Mpc.
All looks well for the last week for all site HVAC fans (see attached).

SHIFT SUMMARY: We've been Locked for over 24hours now and have had a calm day with just some ring heater tests.
LOG:
15:00UTC Detector in Observing and has been Locked for 16hours
- Dustmon for LVEA6 and LVEA10 were going off
17:14-17:15 Went out of Observing briefly to change ring heater settings (73308)
20:16 - 20:17 Went out of Observing briefly to change ring heater settings back (see previous alog)

The past two weeks Camilla has run multiple tests on the ring heaters (73093, 73272, 73289 , 73308), so I updated mag_phase_plotter.py and used it to compare these tests.
It is now easier to add/compare different tests+times with mag_phase_plotter_v1.1.py and the txt file it references, mag_phase_plotter_inputs.txt. Both are currently found in /ligo/gitcommon/labutils/mag_phase_plotter.
Note: We had to replace the LSC-POPAIR channels so we replaced them with LSC-POP_A_RF{9,45} channels for now, and it looks like RF45 is not useful for us when looking at the ring heaters. This will be changed out as soon as we find a better channel.

STATE of H1: Observing at 149Mpc
OUTGOING OPERATOR: Oli
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 12mph Gusts, 9mph 5min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.21 μm/s
QUICK SUMMARY:
All is nominal for H1 thus far this early-evening with H1 approaching 24.5hrs of being locked. Slight increase in the microseismic band for the last 8hrs & winds are mostly under 10mph.
I've made a few updates to my script that graphs the Inlock and OPLEV charges and I've run the code with the latest measurements and included a same time scale (6 months) minute trend of Kappa TST (H1:CAL-CS_TDEP_KAPPA_TST_OUTPUT) that I've scaled the Y-axis a bit for better readability. The codes located at /ligo/home/ryan.crouch/Desktop/Charge_measurements/compare.py and you need to be in the nds2utils environment to run it (conda activate nds2utils). I've also included a solo unmodified Kappa trend.
| Test Mass | Inlock slope | Oplev slope |
| ETMY | -0.18 [V/week] | -0.17 [V/week] |
| ETMX | +0.41 [V/week] | -0.26 [V/week] |
The ETMY charge values seem to be trending down towards zero. The ETMX charge values seem to be converging towards zero as well now (yay?). Kappa_TST appears to be slowly increasing, or slowly decaying with a sign flip.
I've added a test into DIAG_MAIN that shows "Check PSL chiller" when any of the PSL chiller status channels are non-nominal (ENABLED, FLOWERROR, or ALARM). The most likely scenario when this message will show is when the chiller is at a low water level, since if the chiller flow stops or the chiller isn't enabled, the NPRO can't run at all.
Unfortunately, had a lockloss at TRANSITION FROM ETMX (0334utc). Currently on our way back up at ENGAGE ASC.
