What is “Space Weather”?

It has been realized and appreciated only in the last few decades that solar flares, CMEs, and magnetic storms affect people and their activities. The list of consequences grows in proportion to our dependence on technological systems. The subtleties of the interactions between Sun and Earth, and between solar particles and delicate instruments, have become factors that affect our well being. Thus there will be continued and intensified need for space environment services to address health, safety, and commercial needs.
