Effect of Solar Active Phenomena on the Environment Space and its Forecast
Abstract
Investigations of active phenomena on the Sun in recent decades leave no doubt that the state and all significant short-term disturbations of environment space are determined exclusively by solar are events and regions in the corona of the Sun with a magnetic field open to interplanetary space (coronal holes). The interaction of new emerging magnetic fluxes with already existing magnetic fields leads to the occurrence of solar flares (in active regions) and solar filament ejections (outside of them). Observation of the emergence of newm agnetic fluxes, assessment of their magnitude and the rate of ascent allow us to predict solar flares and filament ejections and to estimate the degree of their geo-effectiveness. The main agent that visualizes the propagation of disturbances from solar flares and filaments in the corona of the Sun and in interplanetary space is the coronal mass ejections whose characteristics ideally allow one to estimate the possible disturbances of the geomagnetic field, the possible growth of charged particle fluxes of high energies in environment space. For successful forecast in geo-effective active phenomena on the Sun and their consequences in environment space. It is necessary to know the situation on the Sun for the last 3 days, taking into account the development and characteristics of the current cycle and the epoch of solar activity.
