TITLE: 05/27 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC

STATE of H1: Lock Aquisition

INCOMING OPERATOR: None

SHIFT SUMMARY:

We tried switching seismic blends due to winds in excess of 35-40mph last. Originally the blends were 250mHz+BRS. We then tried 250mHz with no BRS when there was some earthquake activity. We then encountered some earthquake activity that kept us out of commission for  about 1.5 hours. We swicthed back to 250mHz+BRS and had no success keeping DRMI locked. We then switched to 90mHz+BRS as the ground motion started to quiet and that got us past 'resonance' . We then tried switching back to 250mHz with no BRS. With winds staying below 30mph we were able to get to 'resonance'. After only 1 out of 3 good attempts we reverted back to 250mHz+BRS. Winds calming to below 20mph at this time (6:45UTC).
