Ops Day Shift Summary

TITLE: 12/11 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
INCOMING OPERATOR: Oli
SHIFT SUMMARY: Long maintenance day with a great many activities wrapped up late afternoon and initial alignment started around 23:40. The biggest issue we've encountered is that the FSS autolocker is having trouble locking the RefCav; it can grab the resonance but loses it after about a second, so it's been taking quite a while to lock (I manually did it twice this afternoon to speed things along). However, if the FSS is locked, it seems happy, the only issue appears to be with relocking. Otherwise, initial alignment ran smoothly and main locking started at 00:24. Currently up to PREP_ASC_FOR_FULL_IFO.
