TITLE: 08/11 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Austin
SHIFT SUMMARY:

Lock#1:

We rode through a 5.9 from Japan and a 5.1 from NZ which came through within a few minutes of eachother around 00:45UTC (peakmon maxed out at 1100).

Superevent S23081n

Lockloss @ 04:25

Lock#2:

Couldn't get any flashes at DRMI or PRMI, went through CHECK_MICH, still nothing on PRMI, so H1MANAGER took us to initial alignment. Lost it during OFFLOAD_DRMI_ASC, SRM SR2 BS saturations then LL. LSC-POPAIR_B_RF90_I_ERR_DQ starts oscillating and growing a minute of so before we lose it.

Lock#3:

Lost it at OFFLOAD_DRMI_ASC again, same situation.

Lock#4:

Lost it at FIND_IR

Lock#5-6:

The IMC seems to be taking longer to lock, Lost it at DRMI. The flashes were noticibly worse during aquire_drmi so I decided to try and do another initial alignment.

Xarm was struggling and looked weird and was very fuzzy on the scope but the camera image looked fine? The signals weren't converging so I requested XARM to unlocked and it then went into increase flashes then locked but encountered the same issue but it was able to get to offload this attempt and get past green_arms. During SRY the OM suspensions weren't getting cleared so there were a lot of IFO_OUT saturations from OM1_Y and OM3_P.  Finished initial alignment then went back into locking.

Same issue, theres a ringup during DRMI_LOCKED_CHECK_ASC that kills it. I called Keita for some help near the end of the shift and told the incoming operator about the issues and at his suggestion tried to hold us in TURN_ON_BS_STAGE2 since it may be the ASC signals that are causing issues? We're holding here as of 07:00UTC
