TITLE: 01/12 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 67.1386Mpc

LOG:
15:46 UTC John starting clearing snow by CP1
16:13 UTC Starting initial alignment
16:20 UTC Terra called from LLO to ask about our state. They will probably start a test.
16:36 UTC John at end Y clearing snow
16:46 UTC Krishna turning sensor correction at end Y off
16:52 UTC Krishna turning sensor correction at end Y back on
16:58 UTC May have accidently moved PR2 instead of BS during MICH_DARK_LOCKED. Trended back and changed pitch back to previous value. Went back to redo PRM_ALIGN.
17:01 UTC Accidently selected INPUT_ALIGN_OFFLOADED instead of PRM_ALIGN_OFFLOADED. Reselected PRM_ALIGN.
17:04 UTC Karen to warehouse
17:15 UTC Initial alignment complete
17:28 UTC John done clearing snow at end Y, working way back to corner
17:34 UTC Sensor correction had not actually been turned back on at end Y. Reselecting guardian state turned it on.
17:45 UTC Lockloss at INCREASE_POWER. HAM6 ISI tripped.
17:52 UTC Karen out of warehouse
18:07 UTC Lockloss at INCREASE_POWER. HAM6 ISI tripped.

19:02 UTC GRB. LLO is down. Called LLO control room. Joe says he did not receive alert. LLO currently down due to wind.
19:19 UTC Damped PI modes 27 and 28
19:22 UTC Kyle to mid Y to take pictures
19:26 UTC Damped PI mode 27. Had to change phase.
19:34 UTC GRB. LLO is still down.
19:49 UTC Chandra running down Y arm
19:52 UTC Ran passive a2l check: /opt/rtcds/userapps/release/isc/common/scripts/decoup/DARM_a2l_passive.xml. Looks fine.
