TITLE: GCN CIRCULAR
NUMBER: 36345
SUBJECT: GRB 240429A: Fermi GBM Final Real-time Localization
DATE: 24/04/29 15:15:08 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely SHORT GRB
At 15:04:28 UT on 29 Apr 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240429A (trigger 736095873.926064 / 240429628).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 13.7, Dec = 18.5 (J2000 degrees, equivalent to J2000 00h 54m, 18d 30'), with a statistical uncertainty of 8.9 degrees.
The angle from the Fermi LAT boresight is 83.0 degrees.
