A gamma-ray burst (GRB) with the designation GRB 260213A, also known as Fermi Trigger 792697214 and GRB 260213736, was localized using the Fermi Gamma-ray Burst Monitor (GBM) data. The best-fit position was determined to be RA(2000.0) = 155.7 deg and Decl.(2000.0) = -45.6 deg, with a statistical error radius of 1.6 deg and an additional systematic error of 1 deg.

GCN-43722 — GRB 260213A · Fri, 13 Feb 2026 14:20:26 GMT
The Fermi Gamma-ray Burst Monitor (GBM) has detected and localized a short gamma-ray burst (GRB 260213A) at RA = 244.99, Dec = -18.22 (J2000 degrees) with a statistical uncertainty of 11.02 degrees. This event, which occurred on 13 February 2026, is significant because short gamma-ray bursts are rare and powerful cosmic phenomena associated with the merger of compact stellar objects.
