Geomagnetic phenomena refer to various natural occurrences related to the Earth's magnetic field. These include geomagnetic storms, which are disturbances caused by solar wind interacting with the Earth's magnetosphere. Such storms can affect satellite operations, navigation systems, and even power grids on Earth. Another example is auroras, which are beautiful light displays in the sky, typically seen near the poles. They occur when charged particles from the sun collide with gases in the Earth's atmosphere, creating vibrant colors. Both geomagnetic storms and auroras are essential for understanding the Earth's magnetic environment and its interactions with solar activity.
