GCN Circular 36546

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

"At 14:03:51.50 UT on 27 May 2024, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 240527B (trigger 738511436/240527586).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 128.51, Dec = -12.68 (J2000 degrees, equivalent to J2000 8h 34m, -12d 40'),
with a statistical uncertainty of 1.70 degrees.

The angle from the Fermi LAT boresight is 78 degrees.
