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

At 14:07:07 UT on 29 Feb 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240229A (trigger 730908432.025634 / 240229588).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 199.2, Dec = 16.8 (J2000 degrees, equivalent to J2000 13h 16m, 16d 48'), with a statistical uncertainty of 1.2 degrees.

The angle from the Fermi LAT boresight is 85.0 degrees.
