TITLE: GCN CIRCULAR NUMBER: 32708 SUBJECT: Fermi-GBM Observations of High Bursting Activity from SGR J1935+2154 DATE: 22/10/12 20:00:17 GMT FROM: Oliver J Roberts at USRA/NASA O.J. Roberts (USRA/NASA-MSFC), S. Dalessi (UAH) and C. Malacaria (ISSI) report on behalf of the Fermi GBM Team: “The Fermi Gamma-ray Burst Monitor (GBM) trigger 221012599/687277371 at 14:22:46.99 UT on 12 October 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 16 bursts from the direction of SGR J1935+2154 since September 27th 2022. The list of SGR bursts at the time of writing (including the most recent one) is: Date and Time in UTC Fermi MET (s) 2022-10-12T17:39:26.16 687289171 2022-10-12T17:00:47.29 687286852 2022-10-12T16:11:15.04 687283880 2022-10-12T16:00:48.84 687283253 2022-10-12T15:40:10.21 687282015 2022-10-12T15:29:48.48 687281393 2022-10-12T15:14:04.13 687280449 2022-10-12T14:22:46.99 687277371 2022-10-12T12:47:04.40 687271629 2022-10-11T14:11:36.80 687190301 2022-10-11T10:41:16.68 687177681 2022-10-05T21:50:15.79 686699420 2022-10-05T15:35:06.25 686676911 2022-10-02T11:33:41.08 686403226 2022-10-01T20:50:55.74 686350260 2022-09-27T20:51:09.08 686004674 Of these, the following have been misclassified as GRBs: Date and Time in UTC Fermi MET (s) 2022-10-12T15:40:10.21 687282015 2022-10-12T15:29:48.48 687281393 2022-10-12T15:14:04.13 687280449 2022-10-12T14:22:46.99 687277371 2022-10-12T12:47:04.40 687271629 There are many more bursts that did not trigger GBM in the data during this time interval. We report a small burst forest around 2022-10-12T15:40:10.21 UTC. We assume this to be the same burst forest episode as that reported by INTEGRAL (S. Mereghetti et al., GCN #32706) Bursting activity from this source is continuing. We encourage multi-wavelength observations to follow-up this most recent activation.
