TITLE: GCN CIRCULAR NUMBER: 31445 SUBJECT: Fermi-GBM Observations of Recent Bursting Activity from SGR J1935+2154 DATE: 22/01/12 21:42:20 GMT FROM: Oliver J Roberts at USRA/NASA O.J. Roberts (USRA/NASA-MSFC) reports on behalf of the Fermi GBM Team: “The Fermi Gamma-ray Burst Monitor (GBM) trigger 220112832/663710289 at 19:58:04.04 UT on 12 January 2022, tentatively classified as a GRB, is in fact not due to a GRB. This trigger is due to SGR 1935+2154. Fermi-GBM has triggered on 29 bursts from the direction of SGR J1935+2154 since December 24th 2021, some of which may have been misclassified as GRBs.
