We present GRANAT/SIGMA observations of the soft gamma-ray afterglow immediately after the bright GRB 920723. After 6 s, the burst light curve makes a smooth transition into an afterglow where flux decays as t 0:7 for at least 1000 s. At least 20% of main burst energy is emitted in the afterglow. The hardness of the afterglow spectrum corresponds to the power law spec- tral index 1, which is signicantly softer than the main burst.
