TITLE: 08/29 Eve Shift: 2300-0800 UTC (1600-0100 PST), all times posted in UTC
STATE of H1: Observing at 141Mpc
INCOMING OPERATOR: Oli
SHIFT SUMMARY:
H1 had a late-shift lockloss, and was pretty much automated (need INCREASE FLASHES & PRMI), but near the end there was a lockloss at LASER NOISE SUPPRESSION...most likely due to an EQ from Russia. H1's already giving it a go.
LOG:
- 2322-2327 Out of OBSERVING
- 2322 SEI PROC change test to see if it takes us out of Observe--it did (Jim).
- 2323-2327 Elenna working on PRCL FF
- saw these channels ring up on nuc29: CHARD_P, CSOFT_P, CSOFT_Y. Told Elenna so she could turn off her excitation. This also caused a glitch on DARM (nothing on verbal)
- 2327Back to Observing
- 2258-2331Back from MY for measurements (janos)
- 2343-2357 Ion Pump power supply on/off test; said should not affect vacuum or H1 (janos, robert)
- 0040-0107 MY & MX measurements (janos)
- 0347 LOCKLOSS (10hr10min lock)
- 0443 lockloss at LASER NOISE SUPPRESSION
- It almost made it to NLN! But....... After a few minutes it looks like it's related to a M6.0 EQ fairly close from Russia. Saw earthquake signals on picket fence starting up around 0340.
- R-waves just passing through toward end of the shift and see on the picket fence....so it's now making it tough for Green Arms locking (post-INCREASE FLASHES).
