TITLE: GCN CIRCULAR NUMBER: 19788 SUBJECT: Fermi GBM trigger 160810523/492525192 is not a GRB DATE: 16/08/10 15:00:53 GMT FROM: Kilian Toelge at MPE K. Toelge (MPE) reports on behalf of the Fermi GBM Team: "The Fermi Gamma-ray Burst Monitor (GBM) trigger 160810523/492525192 at 12:33:08.74 UT on the 10th of August 2016, tentatively classified as GRB, is in fact not due to a GRB. It is due to local particles. The trigger resulted in an Autonomous Repoint Request (ARR) by the GBM Flight Software owing to the high fluence of the trigger. This ARR was accepted and the spacecraft slewed to the GBM in-flight location."
