STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Camilla (DAY)
CURRENT ENVIRONMENT:
SEI_ENV state: CALM

Primary useism: 0.02 μm/s
Secondary useism: 0.11 μm/s
QUICK SUMMARY:
- We're locked at NLN waiting on the ADS to converge to go into observing
- All systems look good, we're currently riding through a small earthquake
- High frequency noise seems higher than usual
- ITMY8 is slowly rising and has been during each lock today it seems, I may give the gain a sign change
In observing at 23:14, the sign change on ITMY mode8's gain (-0.2 -> +0.2) also is working and bringing it down.
