TITLE: GCN CIRCULAR
NUMBER: 37449
SUBJECT: GRB 240910B: Fermi GBM Final Real-time Localization
DATE: 24/09/10 14:38:24 GMT
FROM: Padraig McDermott at University College Dublin
The Fermi GBM team reports the detection of a likely SHORT GRB
"At 11:42:30.55 UT on 10 September 2024, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 240910B (trigger 747661355/240910488).
The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 171.34, Dec = 29.24 (J2000 degrees, equivalent to J2000 11h 25m, +29d 14'),
with a statistical uncertainty of 7.48 degrees.
The angle from the Fermi LAT boresight is 91 degrees.
