00:00 Due to problems locking left IFO in a down state. 

   Very difficult to do initial alignment and to get the IFO to lock. There was a large amount of activity in the 1 -3Hz and 3 - 10Hz seismic ranges and several periods of higher winds (upper 30 mph and mid 20 mph). Large ring up in Bounce and Roll modes each time reached Engage_ASC stage. Limited success in suppressing these.
