Burns (UAH) reports on behalf of the Fermi GBM Team: "The Fermi Gamma-ray Burst Monitor (GBM) trigger 446348290/150223068 at 01:38:07.99 UT on the 23rd of February 2015, tentatively classified as a GRB, is in fact not due to a GRB. This trigger is due to the outburst from SGR 1935+2154. This is the third such burst that triggered GBM since the outburst was detected by Swift BAT and reported in Burrows et al. (GCN #17485). GBM observations will be reported in more detail in an upcoming circular."
