TITLE: GCN CIRCULAR NUMBER: 38411 SUBJECT: GRB241201B: Fermi GBM Final Localization DATE: 24/12/01 22:15:15 GMT FROM: Bagrat Mailyan at Florida Tech mbagrat@gmail.com

The Fermi GBM team reports the detection of a likely SHORT GRB

"At 13:32:00.63 UT on 01 December 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB241201B (trigger 754752725/241201564).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 333.26, Dec = 38.75 (J2000 degrees, equivalent to J2000 22h 13m, +38d 45'), with a statistical uncertainty of 20.18 degrees.

The angle from the Fermi LAT boresight is 74 degrees.
