DAY Operator Summary
TITLE: 05/14 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Earthquake
INCOMING OPERATOR: Niko
SHIFT SUMMARY:
Somewhat light Maintenance with activities finishing a little after noon.
This afternoon's issue with Initial Alignment stemmed around Input Align and having issues locking X in IR. Sadly not really sure what the issue is here.
Then there was time devoted to PRC_ALIGN in Initial Alignment to fix any issues we have been having lately (related to changes to address the ASC Yaw oscillations we've noticed the last few weeks.)
Handing off an H1 which is still trying to get locked up.
