Ops EVE Midshift Status

Currently Observing at 159Mpc and we have been locked for 30 minutes.

Relocking from the 00:58UTC lockloss took almost three hours due to issues with the PSL/IMC refusing to lock for many minutes at a time or the FSS locking but glitching/oscillating a ton, as well as issues with MICH not being well aligned. Our range was also very low so once we were relocked, I popped out of Observing to adjust the OPO temperature, which is something that Vicky told me I'd probably have to do. Just got done doing that and the range is looking MUCH better - we've gone from ~136 to almost 160Mpc since adjusting the temp, and DARM is looking much better in the higher frequencies.
