"The six Fermi Gamma-ray Burst Monitor (GBM) triggers 269935914, 
269946189, 269952212, 269957694 and 269963785 observed at 06:11:52.75 UT,

2009, in some cases tentatively classified as a GRB, are  not due to a GRBs.

These triggers are all due to local particles events which occurred near
the SAA boundary."
