Observing 1818 UTC
1st attempt:
Green locked all on its own!
DRMI was very close and would frequently catch but on a TEM10. When the try PRMI timer was up, it never transitioned. I'm not sure why it didn't do this yet. So I took it there manually and it locked up quickly, then locked DRMI right after.
Lost lock at ENGAGE_ASC_FULL_IFO. Many sus saturations for a minute or two and ASC didn't look good. Not sure why there were problems at this point, it seemed well aligned.
2nd attempt:
Green locked on its own again!
Find IR COMM was trying to fine tune basically nothing. I brought it to manual and then did a fast search, this worked.
DRMI did not lock, went to PRMI automatically (the DRMI flashes did not look as good as last lock attempt). PRMI locked up quickly and didn't need much ASC tuning.
DRMI just would not catch. I tried tweaking SRM and though I had numerous "mini-locks" and good flashes, I could not get it to lock. Giving up and running and IA.
Initial Alignment:
All automated except SRC align, I wanted to try Jenne's new SR2 states, but I could not select them and the automation ended up fixing whatever was wrong anyway.
3rd attempt:
Green auto locked
DRMI quickly locked
Made it the rest of the way, no issues
SDF:
Only one diff, and it was a high precision with MC3. This is the first time in a long time that I have not had the usual ones.

Doesn't look like the code was loaded in for the new SR2 states. The states screen confused me. We will have to try it out in Tuesday.
