TITLE: 01/31 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Preventitive Maintenance
INCOMING OPERATOR: Jim
SHIFT SUMMARY:
Maintenance Day roughly stopped around 23:00utc (3pm); not tons of activities, but we allowed some work to take us past our noontime "deadline".  Thank you to Patrick, TJ, & Travis helping me out with work I had to pawn off on them.

Immediately upon looking at ALS locking, BOTH arms looked atrocious.  Took a while to finally get away from zero and to a point where the alignment looked serviceable (Jim suggested I probably look at temperatures because of this...or it could be due to all the BSCISIs going down).  At any rate, in the last hour of the shift, I rushed to try and have an aligned H1 to hand off to Jim.

OK, handing an aligned H1 to Jim.
