TITLE: 05/12 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Oli
SHIFT SUMMARY: Several earthquakes today have made trouble for H1 locking today and caused a lockloss this morning, and H1 has been having trouble relocking this afternoon (but things might still be fine).

• 18:30 - Lockloss from EQ - alog77794
• Waited for ground motion to calm down as other EQs passed through
• 20:48 - Reached NLN; mostly automated relock
• 20:52 - Started observing
• 21:13 - Lockloss - alog77797

Relocking has been tricky so far; I've seen the 100Hz PRCL buzzing twice when locking DRMI mentioned in alog77583 (but was not quick enough to catch it before SRM saturated and we lost lock) and the arms have been randomly dropping out while trying to acquire DRMI. The current attempt has gone without issue, though, so I'm unsure if there's an underlying issue I'm not seeing or the IFO is just being fussy on this warm afternoon. Currently up to ADS_TO_CAMERAS.
