The Fermi GBM team reports the detection of a likely LONG GRB
At 20:50:53 UT on 11 Oct 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241011A (trigger 750372658.888186 / 241011869).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 68.6, Dec = -29.9 (J2000 degrees, equivalent to J2000 04h 34m, -29d 53'), with a statistical uncertainty of 7.0 degrees.
The angle from the Fermi LAT boresight is 73.0 degrees.

A. Myers (NPP/GSFC) reports on behalf of the Fermi Gamma-ray Burst Monitor Team:
"The Fermi Gamma-ray Burst Monitor (GBM) trigger 750372658/241011869 (GRB 241011A; GCN [37774](https://gcn.nasa.gov/circulars/37774)) at 20:50:53.89 UT
on 11 October 2024, tentatively classified as a GRB, is in fact not due
to a GRB. This trigger is likely due to local particles."
