space weather

The conditions and phenomena in space and specifically in the near-earth environment that may affect spaceassets or space operations. Space weather may impact spacecraft and ground-based systems. Space weather is influencedby phenomena such as solar flare activity, ionospheric variability, energetic particle events, and geophysical events. See also space; space asset.
