TITLE: 04/15 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 161Mpc
INCOMING OPERATOR: TJ
SHIFT SUMMARY:

With another 4hr wind storm, Squeezing wasn't possible due to a noisy HAM8 & an FC2 mirror oscillating at 0.35Hz.  This wind storm also caused a lockloss.  Initial Alignment was run (skipping SRC).  Winds calmed, and made it to Observing w/ Squeezing due to quieter conditions.  Overall about 5hrs of downtime due to winds preventing Squeezing and causing a lockloss. 
LOG:

• 2335 SQZ_FC takes Out of OBSERVING
  • 2339 Back to Observing after, SQZ_FC relocks....but....
  • 2340 SQZ_FC unlocks again.  Staying down as Naoki investigates FC's ASC
  • In thoughts of prepping for operating with No Squeezing, I did svn commits to all SQZ files which were M-odified.  But we ended up not making changes since the wind storm died.
