I restarted the lock_loss_alerting system at 19:59, it had not been running correctly following the network outage.

Lockloss @ 17:52 UTC

Lockloss @ 17:52 UTC - no obvious cause. There was a small spike in the EQ band at EX around that time, but I don't expect something that small would cause a lockloss.

A couple of disconnected(?) accelerometer channels

The spectra of CS_ACC_LVEAFLOOR_YCRYO_Z, CS_ACC_HAM3_PR2_Y are much lower than the other accelerometer channles.

(i) The channel CS_ACC_LVEAFLOOR_YCRYO_Z has been like that since March 12. 

(ii) The channel CS_ACC_HAM3_PR2_Y has been like that since Jan 30. 

It seems they are either disconnected or having a lose connection.

STATE of H1: Observing at 157Mpc

SHIFT SUMMARY: Currently Observing and have been Locked for 3 hours. Lockloss earlier in the evening needed me to adjust ALSY and move the beamsplitter for MICH/PRMI/DRMI but we went up quickly after that.
LOG:

23:00UTC Detector Observing and Locked for 7.5 hours

02:47 Lockloss
    - ALSY had really high flashes but was struggling to catch until I bumped the flashes up by ~0.02.
    - We ended up going through CHECK_MICH_FRINGES but I was able to get us aligned enough to go through DRMI without needing to do an initial alignment - we'll definitely need to run an initial alignment next time
