Description

The event on 1.08 1983b is the strongest γ-ray burst (S(>30 keV)∼2x10-3 erg/cm2 registrated in the SNEG-2MP9 experiment up to date. There was no fine time structure in the burst light curve, but the burst had a short precursor. The intensity maximum of this burst in the hard 4.5-7.5 MeV energy range precedes the intensity maximum in the soft energy range (39-68 keV) nearly 3s. It is due to the strong spectral evolution
