TITLE: 08/19 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
INCOMING OPERATOR: Corey
SHIFT SUMMARY: Maintenance day today. An early Norco LN2 truck caused some noise before maintenance (alog86437) and a late LN2 truck delayed locked a bit. While we were waiting Elenna was able to get the PRMI ASC working again, yay! (alog86456). I left BRS X sensor correction on while the LN2 truck was filling at EX and we were still able to lock PRMI/DRMI without issue. The BRS velocities seemed relatively calm during that time.
Relocking has been a bit of a struggle and is still ongoing. DRMI is taking very long to lock, and the few times that we have gone past, we've seen DHARD move us away to a lock loss. Right now Elenna and Jenne are working on the issue.
