Friday Ops shift report.

TITLE: 07/17 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY:
While the Earthquake slowly rolled through the site CDS took some time to do some updates and restart the Data concentrator 18:02 UTC 
19:48 UTC CDS seemed to recover.

Ryan C and I were wondering why ISC_LOCK wouldn't get to idle. He traced it through ISC_Lock log and found that the ETM X&Y ESD drivers has not recovered from the power outage. Marc went down there to rest the High voltage. But they still are not working properly and there is a very slow barely noticeable increase to the  H1:SUS-ETMX_M0_FASTIMON_F1_OUT16 channles that seems to be growing. Rahul has been contacted and he's going to look at it and he may leave it in safe if it continues to grow in amplitude.

IMC locking team has been trying to get it locked but has been running into chris-crossed-overed settings and are still activley working on locking IMC.


VAC Team have made gains in getting the vacuum pressures to continue to go down, so Pump down Continues!

Jack team is cleaning up for the weekend.
