STATE of H1: Lock Acquisition
INCOMING OPERATOR: Jim
SHIFT SUMMARY: Frustrating work getting back, but hopefully it will stay this time. See alog38279 for my relocking struggles.
LOG:

• 01:08 Running a2l, out of observing. Around 10Hz was getting worse and LLO was out.
• 01:16 Back to Observing, a2l may have made our range worse?????
• 02:41 Lock loss
• 05:38 Observing
• 05:52 Lock loss
• 00:00 Observing

Summary: I forgot that AS90 is now unreliable because of some test that is going on that I can't seem to find any record of, random connection errors, odd camera image for MICH dark locked, and SRY not locking. Brought back to NLN for 14min before it lost lock again.

Long version:

After the lock loss I tried to relock and had some issues with DRMI. I played around with the alignment a bit and eventually got to lock on what I thought was a PRMI because the POP18 (pink signal on the striptool) and POP90 (light green) were both up, but there was no AS90 (purple). Confused, I tried to figure out where in the SRC cavity the misalignment was, and couldn't find anything but noticed that the spot looked odd for a PRMI. I decided to do an initial alignment and couldn't get Xarm to lock in IR in INPUT_ALIGN. The usual gain trick didn't work at first, but on the third try or so, it finally did. PRC was no issue, but then I couldn't get MICH to lock dark. I would let everything swing and look at the alignment via the camera, and I made it look impeccably symmetric. But when I went to lock it, there was still more light than usual and nothing I did really seemed to change it. I thought that the camera exposure may have been changed or something but looking back at the Guardian it hasn't been changed in a while, and even when I played with the exposure by hand I couldn't get it to look any more familiar. I eventually moved on and then couldn't get SRY to lock at all. I adjusted the spot on the AS_C PD numerous times, I tried adjusting via the camera as well, and nothing seemed to work.

Running out of options I tried restoring all of the optics and then going back to try yet another initial alignment. It was the exact same situation as last time. I eventually got SRY locked, but not because I did anything different. It just felt like working. Okay, then I get back to trying to lock DRMI and again, it seems to lock on a funny PRMI. After banging my head against a wall for a bit I eventually vaugely remember a background conversation while I was doing some other work about someone mentioning that there was going to be some tests with AS90 and the purple trace would not behave normally. So I tried to move on and then Guardian started complaining about connection errors. The channel seemed fine and re-requesting the state solvled the issue. This hapeed a few more times though, no idea what was going on.

After all that there was very little issues and it came right up. BUT as I was writing this it just lock lost. Lovely.

No obvious cause.

SHIFT SUMMARY:

Nice quiet shift with H1 locked for 38+hrs.  Worth note are random visitors to the site who are in the area due to the #Eclipse2017 mania.  :)
LOG:

• 16:47  Noticed Seismon not updating (no alarm, just happened to see message on Diag_main when scanning Wall TVs. (it came back later in the shift).
• Eclipse Traffic:  
  • 18:11 After lunch, happened to spot an RV parked at the LSB entrance.  Then saw some people walking around the desert near the Gate.  Then was contacted via the gate phone.  This was a German teacher and his family in the area for the Eclipse.  Since I didn't want to let them into the Visitor area of the LSB, I invited them to the Control Room and gave them an impromtu tour.
  • 19:30 Another Eclipse visitor (this one was from British Columbia).
  • 20:45 Another German Eclipse visitor (Keita talked to and then steered him to Control Room.
  • 21:31 Another visitor  on site

Noticed Diag_Main message for "Seismon system not updating" at around 16:47.  (Opening up the DIAG_MAIN node's Log, this message came out at 15:36utc (or 36min after Jim's shift ended). 

Jim mentioned that we do not have an action to restart Seismon (he needs to get with Dave B. for troubleshooting).

Now on the Seismon medm, the Keep Alive is still flashing, and I don't see any notes on it about NO Updating.

SHIFT SUMMARY:
LOG:

Recovery from earthquake was rough. Jeff was waiting for violins to settle when I arrived, we got to Low Noise ESD ETMY and ISC_DRMI guardian said somethin about the ETMY ESD not being on. Didn't know what to do, so I pushed the "On" button on the ETMY SUS overview, which broke the lock. After that, I couldn't get past Locking ALS. Not knowing what else to do, I did an initial alignment. When I got to Mich alignment, I couldn't get locked on the dark fringe, at all. I eventually just put the alignment guardian in down and aligned the AS spot by eye, finished SRC and went back to locking. A few attempts at locking PRMI/DRMI and I was able to move on. Violins were a bit high after, but they damped down on their own. Ran A2L, which seemed to take an unusual amount of time to complete.

Back to observing at 9:20.
 

   At mid shift all is well. We are at triple coincident observing. With the wind dropping a little, environmental conditions are good.

I've checked the last suspensions for any sign of rubbing. Preliminary results look like "Nope."
