GRB 230524A: Fermi GBM Final Real-time Localization
2023-05-24T06:16:55Z (15 days ago)
Fermi GBM Team at MSFC/Fermi-GBM <>
The Fermi GBM team reports the detection of a likely LONG GRB At 06:06:35 UT on 24 May 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230524A (trigger 706601200.806822 / 230524255). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 177.5, Dec = 16.3 (J2000 degrees, equivalent to J2000 11h 50m, 16d 18'), with a statistical uncertainty of 3.2 degrees. The angle from the Fermi LAT boresight is 93.0 degrees.
