Received GRB Alert at 18:11UTC.  Going through the checklist (L1500117).

• Checked GraceDB page for alert (UID E189755), and this is NOT a Maintenance Test Alarm.  This has been designated GRB 151004, as detected by SWIFT satellite.
• H1 was in Observation Mode & will be maintained in this state until 19:11UTC
• Tried talking to LLO via TeamSpeak to notify them of the event, but did not hear anything back.  Sent text via chat window.  Then called the LLO Operator (DougL).  He was in the middle or responding back to me via the chat window to say they were trying to respond, but I obviously could not hear them.  Perhaps we need to restart our TeamSpeak sessions.
