Gamma-ray bursts (GRBs) are believed to be due to relativistic outflow of particles from a major explosion interacting with material around the explosion site. Gamma-ray, optical, infrared, submillimetre, millimetre and radio observations of the GRB990123 burst and its afterglow suggest that the initial and afterglow emissions are linked to three distinct areas in the fireball. The peak flux of the afterglow was lower in frequency than other bursts, explaining the short-lived radio emission.
