Space weather forecasting

Definition

Space weather forecasting is the process of predicting and understanding the conditions in space, particularly those influenced by solar activity, and their potential impact on Earth's environment and technology. This forecasting helps anticipate geomagnetic storms, disturbances in the magnetosphere, and their effects on technological systems and human activities, thus enabling better preparedness and response strategies.
