TITLE: 11/06 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Aligning
INCOMING OPERATOR: Tony
SHIFT SUMMARY:
Since there were issues with locking last night/this morning, the main activity of the day was tuning the PSL NPRO crystal temperature again (this was done yesterday during maintnenance).
Attempted locking toward the end of the shift, but had some issues with ALSy---trans power has only been about 0.8 (earlier in the day we were at 0.9). It also goes into stretches of troubles during locking. Tony touched up the alignment and it was able to offload its alignment, but then there was a note about "waiting for PLL DIFF". Currently trying another alignment.

- After alignment went for locking but there was also the EQ. ALSy had troubles with locking. Eventually felt the issue of aligning during the EQ could have caused some grief. Right now Tony is running a new Initial Alignment to see if this helps out ALSy.
