State of H1: Initial Alignment

Intent Bit: Commissioning

Weather: 15 mph wind, light cloud cover

Primary 0.03 – 0.1Hz: 0.01 um/s in Z-axis, X and Y still rung up from wind

Secondary 0.1 – 0.3Hz: 0.1 um/s

Outgoing Operator: Jeff

Quick Summary: Been out of lock for ~21 hours, initially due to high wind but now there are issues with ASC signals not converging and not being able to reach PRC_ALIGN in initial alignment. This carries over to normal locking, where PRMI_LOCKED could not be achieved.
