Ops EVE Shift End

TITLE: 10/17 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Tony
SHIFT SUMMARY: Relocking and at MOVE_SPOTS. We were having a bit of a rough start trying to relock after the lockloss - for the first few minutes ALSX was buzzing weirdly, but then it went away on its own. I briefly checked the quad movements, and it looks like it may have been caused by ETMX Y moving to adjust the alignment. We then were having trouble locking DRMI or PRMI, so eventually I started an initial alignment and that helped a lot.
