Space weather refers to changes in the space environment and the effects that those changes have on mankind’s activities.
The primary source of space weather is the Sun. Variation in the electromagnetic and particulate output of the Sun is the main cause of changes in the Earth‘s upper atmosphere and surrounding regions such as the magnetosphere.
