QUICK SUMMARY:

17:21 UTC a tour group came through the control room.
Confirmed a slow Climb in IMY Mode5. Gain H1:SUS-ITMY_L2_DAMP_MODE5_GAIN was set at -0.04 and I changed it to 0.
Looking at alog 70057 https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=70057  I will try a gain of +0.01

Lockloss 19:50 UTC of unknown cause.   

Locking Summary:
No Initial alignment was done before trying to lock again.
DRMI 1f didn't lock but i let it go to Aquire PRMI which then locked and we went on up.
NOMINAL_LOW_NOISE Reached at 21:04 UTC
Intention bit set to Observing 21:09 UTC.

Violin Modes:
ITMY mode 8 is increasing again. I will take the gain to 0 then then up to +0.04 as described in the following alog.  
https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=70057
That singular change of gain did not make any difference, but taking the gain back to 0 then turning on FM7 which is a -30 deg phase change then bringing the gain back up to 0.04 did start bringing ITMY Mode 5 down. Tagging SUS
