EVE Ops Summary

TITLE:  12/15 EVE Shift:  00:00-08:00UTC (16:00-00:00PDT), all times posted in UTC     

STATE of H1:   NLN 

Incoming Operator:  Nutsinee

Support:  Jenne as Maintenance Re-Locking Commissioner

Quick Summary:

Walked in to Maintenance recovery, and Jenne damped down roll/bounce modes to allow H1 to get to NLN.  Had one lockloss which was a bit of a mystery.
 
See some oscillations on the tidal StripTool of nuc1, and these correspond with notable oscillations on the EY & EX ISIs (see attached).  If the oscillations get worse, Nutsinee may try transitioning to having both 90mHz Blends on for each axis.
Seismically:  useism has slight upward trend over the last 24hrs & slightly breezy tonight (not over 20mph though).
