The alert was received at 01:00:08 UTC. GraceDB said the event actually happened at 00:59:16.64 UTC. We were out of Observing mode for a few minutes for a non-invasive change to ETMX UIM offset from 00:53:12 - 00:59:17 UTC. We think it's reasonable to not veto the alert.
Another GRB alert received at 03:15 UTC (LLO received it first and contacted us). We were at NLN clearing SDF at the time. The data should be good for analysis even though it wasn't in Observing intent (we hit "Undisturbed" button right after).
