TITLE: GCN CIRCULAR NUMBER: 45425 SUBJECT: GRB260822B: Fermi GBM Final Localization DATE: 26/08/22 22:51:06 GMT FROM: oindabimukherjee@gmail.com The Fermi GBM team reports the detection of a likely SHORT GRB "At 20:21:03.83 UT on 22 August 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB260822B (trigger 809122868/260822848). This trigger was initially classified as Below horizon by the flight software, but is in fact a GRB. The on-ground calculated location, using the Fermi GBM trigger data, is RA = 173.93, Dec = 18.48 (J2000 degrees, equivalent to J2000 11h 35m, +18d 28'), with a statistical uncertainty of 6.94 degrees. The angle from the Fermi LAT boresight is 102 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260822848/q...
