TITLE: 07/01 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Oli
SHIFT SUMMARY:
SQZr trouble at the start of the lock but recovered and got to Observing at 00:07 UTC.

H1 was locked fine for 4 hours and 35 Minutes.
Then all the sudden Unknown Lockloss at 2025-07-01 03:56:04 UTC.

I tried to allow H1 to relock itself but it wanted me to find ASL-Y arm by hand and then seemed to get trapped in a PRMI loop. So after about 30 Minutes I did an Initial Alignment.
This did allow for a quick lock of DRMI_1F. 
H1 is currently at ENGAGE_SOFT_LOOPS and locking Quickly.
