Transition To EVE Shift Update

TITLE:  9/13 EVE Shift:  23:00-7:00UTC (16:00-0:00PDT), all times posted in UTC

STATE OF H1:   Continues to be down since earthquakes from just after midnight.  

OUTGOING OPERATOR:  Jim

SUPPORT:  Arrived to a fairly full Control Room on a Sunday (Jenne, Sheila, Evan, Stefan, Jeff K, Greg, Sudarshan).

QUICK SUMMARY:   Ops Overview & O1 CDS Overview look nominal.  (SDF has lots of RED, but since they'be been getting past DRMI a few times, assume we are OK according to SDF [had thought of going back to safe.snaps, but held off on that]).  Will continue troubleshooting.

UPDATE:  H1 BACK!  Jim was still here on-site, so he gets a cookie for his work (along with Jenne [who was here all DAY shift], Sheila, et.al]).

Sounds like they restored IMs to pre-Earthquake/Cheryl alignment values & then did a careful Initial Alignment with Sheila watching them as they went.

Right now we are on our way to recovery:  Addressing SR3 cage servo, SDF diffs, etc.  Currently hovering at about 70Mpc for the last 45mins.  We are listed as "NOT OK" due to current SDF Diffs.

Double Coincidence Status:  Just chatted with Joe H at LLO.  L1 is up, but they are OUT of OBSERVATION Mode for Anamaria/Robert PEM (magnetic/acoustic) injections.  Checked for H1 requests here and Evan may take an hour for a measurement.  

We will coordinate with each other as to when to get back to OBSERVATION Mode.
