On the location of sources of sporadic radio emission observed by means of the ''Ehlektron-2'' and ''Ehlektron-4'' satellites in the 0.7-2.3 MHz frequency range

On the base of experimental data obtained by means of ''Elektron-2'' and ''Elektron-4'' satellites the space-time distribution of sporadic radioemission intensity of the Earth magnetosphere in the 0.7-2.3 MHz frequency range has been investigated. It has been found that the radioemission sources are located in the nighttime hemisphere geocentric distances R approximately (2-6) Rsub(E) and invariant latitudes approximately 60-75 deg S. In the daytime hemisphere the radioemission sources are located more frequently in the daytime polar cusp region, and at the 1110 kHz frequency the radioemission blurred maximum, at invariant latitudes of 66-76 deg S and R approximately (5-8) Rsub(E) is noticeable. For day-, night- and morning time sectors the sporadic radioemission intensities are small at invariant latitudes exceeding 78 deg. This latitude conforms to the magnetic force line outcoming into the magnetotail
