TITLE: GCN CIRCULAR NUMBER: 32497 SUBJECT: GRB 220827A: Fermi GBM Final Real-time Localization DATE: 22/08/27 21:40:19 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM do_not_reply@GIOC.nsstc.nasa.gov
The Fermi GBM team reports the detection of a likely LONG GRB
At 21:30:03 UT on 27 Aug 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 220827A (trigger 683328608.07386 / 220827896).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 113.1, Dec = -1.1 (J2000 degrees, equivalent to J2000 07h 32m, -1d 06'), with a statistical uncertainty of 15.1 degrees.
The angle from the Fermi LAT boresight is 99.0 degrees.
