Ops Shift Log: 04/28/2019, Owl Shift 07:00 – 15:00 (00:00 - 08:00) Time - UTC (PT)

State of H1: Unlocked

Intent Bit: Locking

Support: N/A

Incoming Operator: Niko

Shift Summary: IFO was unlocked due to high winds from the previous evening. Tried relocking and Initial Alignment several times (see times is Activity Log).

Same results despite trying several different alignments tweaks and adjustments.

Summary of Issues:

(1). Could not offload Green WFS as ALS_(X/Y)_WFS_DOF_2_(P/Y)_OUTPUT are not converging. Skipping the offload step a couple of times made no difference. Alignment and locking of GREEN was not a problem.

(2). Skipped GREEN_WFS_OFFLOADED and went on with Initial Alignment

(3). Stuck on PRC_ALIGN no amount tweaking made progress

(4). Skipped PRC_ALIGN and completed Initial Alignment

(5). Tried Relocking

(6). SRM WD tripped – Reset and continued

(7). Still could not get past AQUIRE_DRMI_1F

      Tried several tweaks to no avail

      CHECK_MICH_FRINGES tuned the AS spot to dark but spot looked a bit funky

      Could not get past AQUIRE_PRMI  

(8). Went back to Initial Alignment – to wait for morning support
