TITLE: 01/20 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Earthquake
INCOMING OPERATOR: Oli
SHIFT SUMMARY:
Other than an earthquake lockloss, it was a pretty quiet.....but then in the last 20min we had one of our ETMx Glitches.
LOG:
- 1632 M6.0 Taiwan earthquake inbound
- 1705 EQ mode activated
- 1727 H1 LOCKLOSS (after 3.5hr lock)
- Locking Notes: DRMI looked bad; tried PRMI + CHECK MICH FRINGES and they also did not look good, so moved on to an Initial Alignment 1750--1815); Everything else was automatic.
- 1907 Back to OBSERVING
- 2340 Looking at stuff in the Optics Lab (corey)
- 2351 PSL102 dust alarm
- 0003 Oli noticed the ETMyMode1 violin was ringing up again, so they made the change TJ had found to damp it down in LSC_PARAMS.
- 2109 Lockloss (due to ETMx Glitch)
- Notes: DRMI once again looked bad with no POP18/90 flashes. The camera looked like it was clearly off in pitch; able to get better flashes by taking the BS -0.025 clicks in Yaw---this starting yielding POP18/90 flashes which were above 100counts. PRMI then locked up after 9mins of these flashes.
