Yu (MPE) report on behalf of the Fermi GBM Team: "The following Fermi Gamma-ray Burst Monitor (GBM) triggers 150712.535 (12 July 2015, 12:50:53.84 UT), 150713.123 (13 July 2015, 02:57:44.70 UT), 150713.526 (13 July 2015, 12:37:45.28 UT), 150713.951 (13 July 2015, 22:50:00.78 UT), and 150714.116 (14 July 2015, 02:47:26.04 UT), tentatively classified as GRBs, are in fact not due to GRBs. These triggers are due to particle activity."
