OPS Day Shift Summary

TITLE: 03/15 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Wind
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY:

IFO is LOCKING in ENVIRONMENT

IFO is extremely unstable due to the wind, which during the shift has gone between 30mph 50mph. We have been unable to lock all day, and will likely only be able to relock after 5PM local time (forecasted beginning of the end for gusts).

I stayed in IDLE for times where we were incessantly losing lock but tried locking 3 times when there was a slight lull, which got us up to MAX_POWER, before losing lock again due to wind. (Midshift Report Alog 83387).

Attached is the current state of the EY wind fence. The left pane is totally torn and slid to the left side as seen.

Microseism is also on the rise while EQ activity is low.
