摘要We adopt a recently developed relativistic kappa-loss-cone (KLC) distribution to model energetic electrons energy spectra observed at the geostationary orbit in the storm of 3--4 November 1993. The KLC distribution is found to fit well with the observed data from four satellites during different universal times. This suggests that the electron flux obeys the power-law not only at the lower energies but also at the relativistic energies, and the KLC distribution may provide a better understanding of environments in those space plasmas where relativistic electrons are present.
