Mid-Shift Status: OK to Go Above 10W, Need to Manually Tweak SRM After Engage Soft Loops

Mike & Jenne gave the OK for operations above 10W.

Made it to 25W (after a manual tweak of SRM at ENGAGE SOFT LOOPS to be able to lock the OMC), but had a lockloss at MOVE SPOTS.

Film crew is here and mainly doing set-up in the Multi-Purpose Room of OSB (Richard & Mike are with them).

Keita has been helping me online, Sheila has posted comments in chat, and Jenne said she'd be available remotely now-ish.

Manual SRM Moves at ENGAGE SOFT LOOPS

Attached is the tiny moves made on SRM to lower POP90.

To do this, after ENGAGE SOFT LOOPS was completed, Sheila said to turn off the Inputs to SRC1 pit & yaw and then make SRM adjustments.  I had then kept the SRC1 input OFF and moved on (to that lockloss at MOVE SPOTS.  (Jenne is saying we might want to turn those SRC1 offsets back ON with an offset).
