A geomagnetic storm is a temporary disturbance of Earth's magnetosphere, occurring when a powerful solar wind shockwave or cloud of magnetic field interacts with the Earth's magnetic field.
They are mainly caused by solar events such as coronal mass ejections (CMEs) and high-speed solar wind streams that carry magnetized plasma from the Sun towards Earth.
Effects include spectacular auroras, potential disruptions to satellite operations, GPS navigation, power grids, and high-frequency radio communications. They do not directly harm humans on Earth's surface.
Space weather agencies use a network of satellites and ground-based observatories to monitor solar activity and the solar wind. This data helps predict when a storm might occur and its potential intensity (e.g., using the G-scale).
