What is Space Weather?
Most of the time space, weather is of little concern in our everyday lives. However, when the space environment is disturbed by the variable output of particles and radiation from the Sun, technologies that we depend on in our daily life, in space orbit as well as on the ground, can be affected. Some of the most dramatic space weather effects occur in association with eruptions of material from the solar atmosphere into interplanetary space. Thus, our space weather is a consequence of the behavior of the Sun, the nature of Earth's magnetic field and atmosphere, and our location in the solar system. The increasing deployment of radiation -current- and field sensitive technological systems over the last few decades and the increasing presence of complex systems in space combine to make society more vulnerable to solar-terrestrial disturbances. This has been emphasized by the large number of problems associated with the severe magnetic storms between 1989 and 1991 as the 11 year solar activity cycle peaked.
