TITLE: 02/17 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Corey
SHIFT SUMMARY: Currently relocking and in ENGAGE_DRMI_ASC. After we lost lock right at the end of Ryan's shift, we were able to get back up relatively easily after I ran an initial alignment. We got knocked out by an earthquake though, and we just finished running another initial alignment. The only difficulty in getting relocked for me has been ALSX and Y - they've still been liking to drop out every once in a while, even right after an initial alignment.

After trying and failing to improve squeezing earlier today (two locks ago) with Ryan, squeezing (and subsequently range) also wasn't great when we got relocked this last lock. However, an hour in, we dropped out due to the SQZ filter cavity unlocking, and when it relocked, squeezing was back to being around -4db. Not sure what was changed there, but it got us back to around 155Mpc, which was very appreciated, even if it's not an amazing range.
