TITLE: 11/05 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Oli
SHIFT SUMMARY:
For most of the shift, it was a bit windy, and at around 230pm PT, winds died for a bit. And microseism continues to drop.
PSL group (Jason & RyanS) made a temperature change (there was no PSL Room incursion) and this required changes to the ALS & SQZ lasers (by Daniel & Vicky). H1 made it to NLN just after 3pm PT and then work began with the Squeezer (Vicky, Camilla)....but then there was a lockloss.
H1's currently on its way back to NLN and the hope is the Squeezer will lock after the squeezer adjustments by Vicky/Camilla.
