WHAT IS SPACE WEATHER AND WHY SHOULD WE CARE ABOUT IT?

Abstract

 The impact of the Sun on the Earth is not limited to the fact that during a solar flare a stream of particles is «spit out» and then «hits» our planet, but requires clarification of many fundamental physical phenomena, without an idea of which the solar-terrestrial connections cannot be understood. In a review aimed at non
specialists in space physics, we discuss what space weather is and for whom and for what it can be dangerous. Space weather disturbances affect satellite and ground-based technological systems, so at least a superficial understanding of the mechanisms of such an impact is necessary for those who deal with such systems.
