Ops Eve Shift End

TITLE: 06/12 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Observing at 144Mpc
INCOMING OPERATOR: Ibrahim
SHIFT SUMMARY:

Currently Observing at 145 Mpc and have been Locked for over 8.5 hours. The wind is still a bit elevated and not very consistant. We do have an eaerthquake coming in, but it doesn't look like it'll be too bad (although it might cause a lockloss if the wind doesn't go down a bit).

I turned the roll damping off and accepted the sdf.

Occassionally PI24 will ring up and cycle through all the phases until it gets back to one that works, so I really need to work on that guardian and fix that. Luckily though, we haven't needed to do XTREME_DAMPING, so we've been able to stay in Observing during those ringups.

LOG:
