TITLE: 10/18 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 156Mpc
INCOMING OPERATOR: Corey
SHIFT SUMMARY:
IFO is in NLN and OBSERVING as of 21:19 UTC.
A few significant events:
PSL Maintenance: Sheila and Vicky re-reduced the NPRO current - alog 80746
Fast Shutter Weirdness: Upon reaching NLN, we could not go into observing because the shutter guardian was registering the shutter as closed/not working. After the initial shock, it was determined through trends that this was just a Guardian thing, rather than yet another broken toaster. alog 80749
EY Timing Glitch: Dave noticed an 800ns timing glitch with no consequences - alog 80742
Locklosses: Two PSL FSS Related Locklosses: alog 80748 and alog 80741. Both before the PSL change and none thereafter.
SQZ Adjustments: Went out of observing briefly to optimize SQZ angle and temp.
PIs: PI 24 and 31 rung up heavily today but were successfully and automatically damped, causing no locklosses.
