TITLE: GCN CIRCULAR NUMBER: 34198 SUBJECT: GRB 230709C: Fermi GBM Final Localization DATE: 23/07/10 20:07:49 GMT FROM: Peter Veres at University of Alabama in Huntsville <veresp@gmail.com> The Fermi GBM team reports the detection of a likely SHORT GRB "At 17:38:26.82 UT on 09 July 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230709C (trigger 710617111/230709735), which initially was classified as a non-GRB trigger by the flight software. The on-ground calculated location, using the Fermi GBM trigger data, is RA = 267.56, Dec = -70.47 (J2000 degrees, equivalent to J2000 17h 50m, -70d 28'), with a statistical uncertainty of 1.44 degrees. The angle from the Fermi LAT boresight is 131 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2023/bn230709735/q...
