What is the main purpose of space weather forecasting?

• A. To predict solar flares, coronal mass ejections, and their effects on satellites, power grids, and communications.
• B. To forecast Earth's weather.
• C. To map the cosmic microwave background.
• D. To track meteor showers.

Answer: (A)

Space weather forecasting centers on solar activity and its impact on technology and human activities in space and on Earth. Its main purpose is to predict events like solar flares and coronal mass ejections and how their energized particles and radiation can affect satellites, power grids, navigation and communication systems, and other infrastructure. With advance warnings, operators can take protective actions—putting satellites into safe modes, rerouting or resizing power demand to mitigate geomagnetic storms, and ensuring reliable communications and aviation routes where radiation exposure is a concern. The other options don’t fit because terrestrial weather is a different field, mapping the cosmic microwave background is about studying the early universe, and tracking meteor showers concerns observing space debris and meteors rather than the Sun’s space-weather impacts on technology.
