Distribution of gamma ray fluxes at altitude 500 km: Coronas-I data

Results of the statistical study of gamma ray fluxes in the energy channels 0.12 - 0.32 MeV, 3.0 - 8.3 MeV,measured by the instrument SONG on board th e low altitude high inclination satellite CORONAS-I are presented. The geog raphic maps based on sets of data in March June 1994 are constructed as wel l as latitudinal distribution (i.e. the variation of average fluxes with ve rtical cut - off rigidity) for higher energies is given. The irregular spat ial structures of gamma ray flux increases in subauroral zone and at lower latitudes are discussed.
