Maintenance activites ended just before noon, and then locking commenced. (times in UTC)

1855: Started initial alignment.

• Requested the INITIAL_ALIGNMENT state from ISC_LOCK. This gave the INIT_ALIGN node control and it began aligning the green arms.
• The INIT_ALIGN node did the entire alignment except for a few small tweaks for the green alignment. The rest of the alignment I just monitored to make sure there was no funny business.

1907: Inital alignment complete, starting locking.

• Quickly got to a locked PRMI, then 5min later a DRMI. ASC here was a big far off so we opted to wait it out a bit to make sure the signals were well settled. After a handful of minutes we lost lock for no apparent reason.
• Repeated the above with the same outcome.
• Repeated the above with sucess. Did nothing different, nor do we know why we were losing DRMI.

2038: Reached DC Readout.

• Here we will stop for some commissioning work.
