We were in EQ mode for a 4.8M EQ from Canda. The ground had mostly calmed down when we lost lock, but the high microseism may have contributed.

There is a microseism SEI_CONF state but I'm not sure how that works with the new automatic SEI_ENV. Tagging SEI  to ask what is currently the best state to be in when microseism is high? (Secondary useism: 0.38 μm/s)

This level microseism should not be a problem for the nominal configuration. It needs to be up around 1 micron/s to be an issue. If the microseism gets that high, we will have to do some work on the seismic automation, but we're unlikely to see that kind of ground motion this time of year.

Great, thank you Jim.

DRMI is Locked. After 25 minutes verbal alarms asked me to find y-arm by hand. By this time INCREASE_FLASHES had already got flashes to 0.8 and WFS had grabbed. 
Had to intervene at FIND_IR. Should look at what has changed here as this seems to have happened a few times this week. Will add to Trello board.
