✦ Synopsis

In this paper, the dependence of the intensity of solar bremsstrahlung in the spectral range from 1-60 keV on heliographic longitude is investigated. Considering a flare mechanism, which assumes that the electrons move in a preferred direction in the course of their acceleration (according to the model of Takakura and Kai (1966) the electrons move parallel to the solar surface), we come to the conclusion that the maximum of the bremsstrahlung intensity is shifted with increasing electron velocity towards the direction of motion of electron beams. In the case of the Takakura and Kai flare mechanism, the slow electrons (fl= @0 -)0), i.e. with small energies of 1-10 keV, reach the maximum of the bremsstrahlung intensity round the CM; for higher velocities (fl= 89 i.e. for higher energies of 10-60 keV, the direction of the maximum is shifted away from the CM towards the disc limb. These theoretical conclusions were proved by experimental research conducted by means of satellites.
