OPS Day Shift Summary

TITLE: 06/03 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: Oli
SHIFT SUMMARY:

IFO is in PLANNED ENGINEERING and LOCKING

Productive light maintenance tuesdays in which most of the work was done checking annulus pumps (VAC) and doing cable work on ISCT1 (EE). After this, we begun locking again.

There was also some GC/CDS work done with the internet, which has concluded. Other than that, normal Tues Maint. activities such as tumbleweed removal and NORCO took place.

We were able to sit at MAX_POWER for quite a while, before comissioner-caused lockloss.

DRMI ASC now works but more work needs to be done on PRMI ASC. This means that after a manual initial alignment, we can get to MAX_POWER automatically.

The majority of the work now is being done fixing an issue thought to be mainly with ADS (and soft loops that engage during and after POWER_UP.

The plan for then night can be found in Oli's alog 84765
