— long test of global interlocks

— almost finished tuning check of survey and target installation

== Electronics

— testing will start when things are more quiet on site (repairs and checks, etc.)

— in 2023 the short was repaired (via cleaning) and external resistor was removed

— dB can be updated

— Working with Richard Thrutchley to have enough statistics for SC

— Yuri sees ~1 mrad rotation in survey

— needs survey uncertainties to verify

— Alexei mentioned survey target appears to have dropped in position by as much as ~1.5 mm
