Title:  02/05/2015, Day Shift 16:00 – 00:00 (08:00 – 16:00) All times in UTC (PT)

Support: Kiwamu, Jim, Masayunki, Jenne, Jim W.              
 
Incoming Operator: Travis

Shift Detail Summary:  After an initial alignment, spent most of the morning trying to relock. Still losing lock at DRMI_LOCKED. Kiwamu looking into the problem, found the SR3 Cage Servo was noisy, which may be causing the lock loss problems. About this time, there was a mag6.4 earthquake in Taiwan, with an R-Wave velocity of 5.3um/s. The seismic signal rang up to ~ 3.0um/s. Put the IFO into down until things settle down.

After seismic rang down from EQ tried relocking. Had to tune MITCH_DARK. All other alignments were OK. Relocked at NOMINAL_LOW_NOISE. Turnover to Travis and the commissioners.
