TITLE: 07/23 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Preventive Maintenance
INCOMING OPERATOR: Travis
SHIFT SUMMARY:

During a fairly busy Maintenance, I did not hear that the TCSy laser went off at 11:42am.  Noticed it at about 2:14pm, so ITMy was cold for almost 3hrs.  These extra hours of downtime needed to heat up ITMy were totally my fault!
