OPS Thursday Day shift summary
TITLE: 02/12 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY: Dave did some CDS restarts early in the day, alog89133, and alog89130 and again at the end of the day. Secondary microseism has gone up quite a lot in the past 9 hours, presumably from the 10.5m (windy.com) waves crashing into the Juneau/Ketchikan area north of Washington state. VAC team left an AUX cart pumping down by HAM4. HAM1 alignment and EOM crystal work continued today.
