Jenne's MC1 bump seemed to have stopped some thing from rubbing : See her alog here.
That seemed like it was the solution to some of out lockloss issues.
Eric returned back from EY Chiller and we noticed that the EX chiller change had brought the H0:FMC-EX_CY_H2O_SUP_DEGF temps back down
19:14 MOVE_SPOTS -> LOCKLOSS
19:52 RESONANCE -> LOCKLOSS
21:38 NLN_ETMY !!
Sus charge measurements were completed!
21:46 LOCKLOSS from NLN_ETMY
22:20 Jenne Making Ref CAV adjustments which may be the cause of many Locklosses at Locking ALS due to the IMC losing lock.
The Old camera computer will now run the New Camera Software locally (instead of standard) which is must faster now! Details found in the Operator chat channels.
Diff beatnote is low. Tried to touch up the Beam Splitter to get a better DIFF beat note.
Decided to do an Initial Alignment based on the ALS CAMS
