This trigger is due to 1E 1841-045 / Kes 73.\n\nAdditionally, Fermi-GBM trigger 240821366/745922867 at 08:47:42.97 UT on the \n21st of August, tentatively classified as a GRB is also believed to be \nfrom 1E 1841-045 / Kes 73.\n\nFermi-GBM has triggered on 8 bursts from the direction of this source since \nits reactivation on August 20th 2024. \n\nThe SGR bursts from this source at the time of writing are:\n\nDate and Time in UTC        Fermi MET (s)\n2024-08-22T11:36:36.13       746019401\n2024-08-21T20:29:24.33       745964969\t\t(Reported by Swift, GCN 37222)\n2024-08-21T12:16:10.19       745935375\t\t(Reported by Swift, GCN 37222)\n2024-08-21T09:27:49.83       745925274\n2024-08-21T09:07:06.82       745924031\n2024-08-21T08:47:42.97       745922867\n2024-08-20T19:01:18.89       745873283\t\t(Reported by Swift, GCN 37222)\n2024-08-20T18:39:13.66       745871958\n\nThere are likely more bursts in the sub-threshold GBM data since the reactivation of this source.\n\nBursting activity from this source is continuing. \n\nWe encourage multi-wavelength observations to follow-up this most recent activation.\n\nFor Fermi GBM data and info, please visit the official Fermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"",
