Koval Advances in solar bursts observations by the low-frequency radio telescopes of a new age Abstract.The GOES data for the flare proton energies of 10 -100 MeV are analyzed. Proton fluxes ~ 10 32 acceleration takes at the current sheet decay. Proton acceleration of in a flare occurs along a singular line of the current sheet by the Lorentz electric field, as in the pinch gas discharge. The pulse of protons duration is by 2 -3 orders of magnitude longer than the duration of flares. The high-energy proton flow from the flares that appear on the Western part of the solar disk arrive to Earth with the time of flight. These particles propagate along magnetic lines of the Archimedes spiral connecting the flare with the Earth. Protons from the flare on the Eastern part of the solar disk begin to register with a delay of more than three hours. Such particles cannot get on the magnetic field line connecting the flare with the Earth. These protons reach the Earth, moving across the interplanetary magnetic field. The particles captured by the magnetic field of the solar wind are transported with solar wind and due to diffusion across the magnetic field. The patterns of solar cosmic rays generation demonstrated in this report are not detected during the small (Ф ≤ 1 см -2 с -1 стер -1 ) proton events. IntroductionAbout 30% of big flares (class X and even less class M) are accompanied by a flux of relativistic protons. Part of these protons hits the Sun and causes nuclear reactions. The other part of the protons propagates into the interplanetary medium. Despite decades of the effort, the relativistic flare protons remain the least studied manifestation of the flare [1]. The energy of the charged particles in the interplanetary plasma can change only due to the emission or movement along the electric field MdV/dt = eE + e[V×B]/c. The change of the energy of a particle moving in the field is dW = eE r dr. The electric field may be of different origin: the field of another charged particle (at a collision), space charge field, in particular due to polarization of charges in the plasma, the field induction dB/dt, etc. At the scattering by inhomogeneities of the magnetic field the particle can change the energy only due to motion in the electric field associated with a magnetic field fluctuation. This was clearly articulated in the well known work of Berezhko E. G., and Krymsky G. F. [2]: "Possibility of charged particles acceleration in the plasma in the related electric fields." The change of the energy at scattering by a magnetic fluctuation is determined by the magnitude and spatial scale of the electric field in such fluctuations Two possibilities of solar cosmic rays generation are discussed in the literature: a). Proton acceleration in the Lorentz electric field E rec = -V rec ×B cs /c along the singular lines (in particular the line B=0) in the current sheet during magnetic r...
