The brightness of GRB 230307A is remarkable, with a measured duration of *T* 90 ≈ 35 s and an exceptionally high prompt fluence of (2.951 ± 0.004) × 10 −3 erg cm −2 in the 10–1 1). This burst is so bright that it was detected by several other high-energy instruments, enabling source triangulation by the InterPlanetary Network (IPN).
Detected by Multiple Instruments
