GRB received at 21:12:30UTC, kicks IFO out of observing, back now

19:40:08UTC - IFO in Observe

21:12:30UTC - GRB arrives and updates an EPICS record that kicks SDF into RED, and drops IFO out of Observe

21:19:10UTC - IFO back into Observe

 

At this time, there's no indication that anything other than the change in an EPICS record occurred.

THE DROP FROM OBSERVE MODE AT 21:12:30UTC was NOT a change in the IFO, and ALL DATA 19:40UTC to the end of the lock (currently the IFO is still locked) are GOOD!

It appears that the GRB alarm disabled injections, so GWIstat is OK but yellow.  Tj and others are looking into it.
