Transition to DAY Log

TITLE: 05/16 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Cheryl
CURRENT ENVIRONMENT:
    Wind: 6mph Gusts, 4mph 5min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.14 μm/s
QUICK SUMMARY:

H1 is down in the READY state due to problems  (i.e. alignment issues, IMC SUS OSEM glitches, etc.).  The OBSERVATORY MODE tool was in the "locking" state, so I transitioned it briefly to "COMMISSIONING" since [I thought] H1 is still set for higher power operations [heard this was backed out], but then second-guessed that since we really are having overall issues with H1 and will be taking us to the CORRECTIVE MAINTENANCE state (one should feel free to file an FRS....I can possibly do that).  Let's stay in the CORRECTIVE MAINTENANCE state and mark this down time until we get back to OBSERVING.  Waiting for reinforcements to arrive.

Cheryl posted an alog about possible noisy REFL signal.

I got on the LIGO Virgo Control Rooms teamspeak channel to apprise other operators of H1's status/plans.
