TITLE: 11/22 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: Tony
SHIFT SUMMARY: Trying to lock DRMI, and we've been having some issues locking for the past four hours, but I think it might be a combo of the high secondary microseism and a medium sized earthquake that passed through? Hard to tell for sure.
