TITLE: 07/29 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 53Mpc
INCOMING OPERATOR: Corey
SHIFT SUMMARY:

Spent about 2.5 hours damping violin modes at NLN before losing lock and having the fundamentals ring back up again. I decided it might be best to go directly to observing after getting back to NLN despite the violin modes.
