An X-ray afterglow was discovered by the Beppo-SAX satellite following the gamma-ray burst on Feb 28 1997. A substantial proportion of the gamma-ray burst's total energy was contained in the X-ray transient. A multi-wavelength observational campaign was inititated by the quick detection of the gamma-ray burst that led to the discovery of a fading optical transient. The Beppo-SAX measurement explains the link between the location capability of radio, optical and X-ray astronomy and the gamma-ray phenomenology.
