OPS Eve Shift Summary

Title: 10/30 Eve Shift 23:00-7:00 UTC (16:00-24:00 PST).  All times in UTC.

State of H1: Observing

Shift Summary: After the wind calmed to a reasonable level a few hours into my shift, I began a slow progression of locking.  I got to do a few things that were new to me, such as being involved in restarting a (really) frozen guardian node, and engaging the ISS 2nd loop manually.  Locking in Observing after engaging 45 mHz blends.  Microseism coming up slowly.  Winds calm, at last.
