OPS Day Shift Summary

TITLE: 12/09 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Earthquake
INCOMING OPERATOR: Oli
SHIFT SUMMARY:

IFO is DOWN due to Earthquake

H1 was only able to lock for 36 minutes today (lockloss alog) in between earthquakes. It's been a very quakey day with:

We tired locking after the first 6.3 magnitude EQ died down only to have another 6.3 magnitude EQ 3 hrs later (and then another 6.3 10 mins after that). I've attached a screenshot of our microseism. The secondary microseism is also over the 90% threshold, which makes us more succeptible to lower mag EQs. We've been in useism and earthquake mode all day essentially.
 

LOG:

None
