Since the platforms are unlocked, closing the loops seems right. No issues with HEPI. The ISI drives seem a bit high for level 1 even though I zero'd out the position biases. THis could just be the purge air or neighboring floor activities.
HAM5 SR3: magnets found, osems to replace, lock up sus until HAM5 isi balanced. Most morning locking and BOSEM adjust
BSC3: rebalanced BSC3 & locked ISI for SUS (ACB swung back)
BSC1 (Travis): checked ESD cables (some issue), coarse PIT work complete & ready for IAS check, spool out & ready for IAS (will take ~day for set up), really want to determine if a HEPI translation will be needed, because this would be a major schedule hit
EX Vent Prep: Laser Hazard at EX, Sheila staged for QPD work, EX first cleaning complete (2nd cleaning Fri or Mon), Doors off on Tues, 1st week: ISC & PCal 2nd week
HAM4 TF: tripped last night, so will want to run 8hr TF (after Apollo noisy work): avoid noisy work near HAM4
Output Arm Oplevs: ready for HAM4/5 retroreflection
Viewport Inspection work brought up with chambers being closed soon.
Business:
please see attached. only unexpected h1fw0 restarts up to the time the solaris QFS box was power cycled.

Today we finished setting back the optical lever at ETMx, all went well, we just need to check for digital comp filters.
Pulled the covers away from the ISI table. Attempted to close position loops on HEPI but was not stable in horizontal, decided to leave it off. After I got the TFs started, I looked again and found the HP L4C blend filter off so this signal was getting through and I'll guess is the problem. Don't want to stop the TF so I'll check that tomorrow.
After turning on the HP (horizontal pringle) L4-C filter, the position loops work just fine.
Andres R. & Jeff B. We reglued the second magnet broken off the Intermediate Mass (the Lower Left). There were no problems encountered during the repair. We will remove the jig after 24 hours. If the bond is good, we will remount and align the BOSEMs and put the baffle (mover for access to the magnets) back into its position for ISI balance work. Both broken magnets were removed from the chamber.

eth0 on script0 was running at 100/Full instead of 1000/Full, so a number of things were likely taking longer to run on it (most notably the daily pull of the aLog and SVN backups). I un/replugged it to get it to renegotiate at 1000/Full, and restarted the screenshot processes to ensure that the web pages will stay current.
The adapter spool at GV 5 has been removed and the hard cover with the custom slots for IAS placed on the Y arm tube.
Apollo Scott, HughR, GregG, JimW The 3rd 3IFO BSC-ISI went into the can this morning, and is sitting in the SB garage waiting for transfer to the LVEA. No problems, we were done before it got too hot by 11. After Scott helped me flip and move the first plate for the 5th, and final, ISI onto the test-stand. Unit #4 is on the other test-stand and awaiting some parts from clean and bake, before we can start testing.
I went into ITMX to rebalance this afternoon. Largely uneventful, all I had to remove was optical table ballast that compensated for fiber-guards missing from the wire-hang, and everything went right to where it belonged. The ISI is now re-locked, and SUS's optic covers are re-installed. ITMY won't be so easy, because it is missing the compensating ballast. When we re-balance, it will have to be done by removing weight from the sides of stage 2. I would prefer we did that before we jammed the ACB in there, if at all possible.
After the alignment of the ITMX, I failed to do this to capture the 70urad yaw we are holding. I was checking for tilts caused by the ACB swing out and notice some large position shifts wrt free hang locations. There must have been a reboot/burtrestore ~ 1 July. The ACB being swung out has tilted HEPI ~5urad RX an ~20urad RY. This should not impact our balance but I can hold it with HEPI. I set the location targets to the 70urad rz and these tilts and the otherwise free hang position.
OK so remember the safe.snap!
I placed the IR oz optics fiber coupled laser on ISCEX, with a colimator and two steering mirrors.
When I first got there the green QPD cenering servos were not working, it seems that the matrix elements changed in early june so I did a burt restore to June 1st. The servos worked fine after that.
I only saw one green beam in the IR trans path at the PD this time, this is different from what I saw in May (alog 12161). I aligned the IR laser along the path of the green light coming out of the chamber using the mirrors I had added to the table, and saw a retroreflected beam coming back out of the chamber. This beam is somewhat large.
I'm done using the laser at end X, and have returned the key to the control room. If anyone wants to transition to laser safe while preparing for the vent, that's fine.

Dan found a possible memory issue with h1ldasgw0. He forced a system core dump both in the bad and good states for follow up with Oracle. He then power cycled h1ldasgw0 and we restarted h1fw0 daqd process to see if a power cycle recovery differs from reboot.

Andres R. & Jeff B. We reglued the UR magnet on the SR3 Intermediate Mass this morning. We will check the bond tomorrow. When all is well with the repair of the UR magnet, we will replace the LL magnet, which was also knocked off. Both missing magnets have been found and are not in or on the suspension. To use the magnet repair jig we had to remove the baffle located behind SR3. Its location was marked. The baffle will be returned to its installed position when the magnet repairs are completed.
