Ops Day Shift Summary
TITLE: 05/24 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
SHIFT SUMMARY: We had a late start to the run but managed to get a 5 hour lock in. We lost lock for reasons unknown so far. Sheila and I went into ISCT1 to fix the beatnotes that we've been struggling with for the last ~9days after reverting PR3 to its old values. We are now about to start an initial alignment with the new table alignment.
