OPS Saturday day shift start
TITLE: 09/21 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Aligning
OUTGOING OPERATOR: Oli
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 10mph Gusts, 5mph 3min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.15 μm/s
QUICK SUMMARY:
- We're in an initial alignment
- Lost lock at 12:38 UTC
- NUC33 froze again, so I power cycled it
H1 had been stuck in IA for 1.5 hours, something was clearly yawed from the camera. I looked at the osems scopes for the PRC and the ITM, ETM, TMS and set the test mass sliders to recover the osem values from when we were locking on the 20th. ITMY_Y ended up having to be moved the most, now we're moving along IA at regular pace.
