Ops Shift Log: 01/26/2020, Evening Shift 00:00 – 08:00 (16:00 - 00:00) Time - UTC (PT)

State of H1: Relocking  

Intent Bit: Locking

Support: N/A

Incoming Operator: Corey

Shift Summary: IFO broke lock at 03:39 (19:39) with an I_Y message on Verbal_Alarms. Problems again with DRMI-1F and PRMI. Put a halt to locking, for the passage of a mag6.3 EQ from the Solomons. After EQ passed, back into WINDY and ran Initial Alignment, which completed with a tweak to ETM-Y and TMS-Y in pitch and yaw.    

Tried relocking. Made it to LOWNOISE_ASC when lock broke. This attempt was the second time this evening the locking process made it past DRMI_1F. It was also the second time the lock broke at LOWNOISE_ASC.

Trying to lock again. Still not making it past DRMI_1F. Turning over to Corey. Perhaps he will have better success.
