TITLE:    Dec 26 EVE Shift 00:00-08:00UTC

STATE Of H1: Observing

SUPPORT:GregM

SHIFT SUMMARY: Quiet shift. Lost lock, be re-locking was easy. LSC started drifting for a couple hours before the loss, but nothing else looked bad.

ACTIVITY LOG:

0:30 Dale brough a large tour into the CR. They behaved themselves.

5:00 LSC-POP started a slow trend down, not sure what the cause was. Alignment drift?

6:30 Lockloss, LSC-POP continued its downward drift, then RF90 started going limp, then lockloss. I attach lockloss plots, but I think this started an hour or two before.

6:45 I start an initial alignment because ALS-Y won't lock. I had to touch TMSY some, but only small tweaks.

8:00 Back to observing.
