TITLE: 09/10 Eve Shift 23:00 – 07:00 (16:00-00:00), all times posted in UTC

STATE of H1: Observing

INCOMING OPERATOR: Corey

SHIFT SUMMARY: Sudden lockloss with SR2 saturation. Went into initial alignment after not being able to lock PRMI, but MICH_BRIGHT didn’t seem to work that well so I did MICH_DARK_LOCKED alignment and redid SRC_ALIGN. After that I lost lock from CARM_TO_TR, and then managed to reach NLN.
