"The Fermi Gamma-ray Burst Monitor (GBM) trigger 737076431/240510977 at 23:27:06.88 UT
on 10 May 2024, tentatively classified as a GRB, is in fact not due to a GRB. 
This trigger is likely due to local particles.

We advise the community that due to the current geomagnetic storm and intense solar activity, 
GBM is triggering regularly on such events."
