QUICK SUMMARY:
IFO is DOWN for Planned Tuesday Maintenance
When I arrived, IFO was about halfway through locking.
Was locked for only 3 minutes at NLN and unlocked due to a DCPD Saturation at 14:41 UTC
Dust monitors were sounding and were acknowledged.
For the 14:41 lockloss, the signals look fine on the lockloss select tool scopes. The violins also look fine, they were all trending downwards. The OMC_DCPD signals looked interesting, they seem to have been diverging before the lockloss.
