TITLE: 03/24 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM

    Primary useism: 0.03 μm/s
    Secondary useism: 0.27 μm/s
QUICK SUMMARY:

H1's been down and Ryan S shared issues he was observing (see what he says about ALSy  in an upcoming alog).  He was running an Initial Alignment during our shift handoff.  Arm locking was fine, but DRMI looked pretty bad.  Went through PRMI a couple times (was successfully completed) as well as a round of CHECK MICH FRINGES---DRMI still looked bad.  Now running through a 2nd consecutive alilgnment.

Winds are much calmer (under 20mph) than last night and microseism.
