Physical aspects of solar flare predictions.
Abstract
The authors review physical significant signs of a flare process with a sufficient advance. These signs appear in optical and radio waves and reflect either the process of the emergence of a magnetic flux in the active region or the collisional process of two bipolar fluxes with the 1 - 2 days precedence. A new flux, flare and filament are interconnected phenomena. The filament evolution gives some flare precursors such as the fibrill turnings, the filament plot broadening, the hardbody rotation sites, etc. The magnetic reconnection process is reflected by the noise storms, "the peculiar detail" at 2 - 4 cm wavelengths, the dm - wavelength long period oscillations, and the spectrum slope of cm - waves.
