SHIFT SUMMARY: The range was in the 150s, "PSL_ISS diff power is low" notification was flashing occassionally on DIAG_MAIN. We've been locked for 5:30

21:45 UTC Lockloss

23:05 - 23:30 UTC The violins got a little rung up by either of the locklosses so we had to damp them in OMC_WHITENING for a bit

23:30 UTC Observing

23:43 UTC 12 disconnected chans on CDS overview, NUC33 (cdsws04) froze, I had to physically restart it to get it back. This cleared the dc'd chans as expected.
