TITLE: 12/28 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Wind
INCOMING OPERATOR: Oli
SHIFT SUMMARY:

Winds put us over the tipping point for not making it possible to Lock H1 (with the continued horrendous µseism); so marking Observatory Mode at WIND state.  For the latter part of the shift, took H1 to IDLE (to help prevent ringing up violins).

With H1 down, attempt a full Site Walkthru to the End Stations (only made it to EY).
