TITLE: 10/22 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
INCOMING OPERATOR: Ibrahim
SHIFT SUMMARY: The furthest I've been able to get was MAX_POWER, I had several high state locklosses at different states (REDUCE_RF45, MOVE_SPOTS, MAX_POWER). I minimized the SHG rejected power while relocking as I saw the notification. After the second IA things went pretty well at first, microseism was still at about the same level as earlier. One of our locklosses at ALS had a BRS_GLITCH tag, which are rare. All of the LLs had an ADS_EXCURSION tag and most of the higher state locklosses I saw a ~4.5Hz oscillation in MICH. I started another IA at 21:45 as DRMI is taking a while to lock and it ran through CHECK_MICH on the last aquistion. Microseism has remained elevated and even increased a tiny bit. The IMC is really struggling to relock after INPUT_ALIGN, its been trying for the past 6 minutes as of 05:00.
