Friday AM locking
- Initial alignment, no problems after IFO had cooled down from TCS work.
- Tried some PRMI to DRMI (alog 45756) since DRMI didn't want to catch.
- Locked, increased power to 28W, sat there for several minutes. Had opened SRC ASC loops, Hang was adjusting the rad press comp gains, Danny put TCS CO2s to new values found last night. Other than that, no adjustments to configuration (ISS was never DC coupled during this lock). Some low frequency angular something blew the lock, not a fast lockloss.
