May 2024 Geomagnetic Storms: Historic Auroras

2024-05-15

In May 2024, Earth was struck by a series of intense geomagnetic storms Geomagnetic Storm: A geomagnetic storm is a temporary disturbance of Earth’s magnetic field caused by solar activity, such as CMEs or solar flares. These storms can disrupt technology, navigation, and create auroras far from the poles. triggered by powerful coronal mass ejections (CMEs) Coronal Mass Ejection (CME): A CME is a massive burst of solar wind and magnetic fields released from the Sun’s corona into space. When directed toward Earth, CMEs can trigger geomagnetic storms, affecting satellites, power grids, and producing auroras at unusual latitudes. from the Sun. These storms produced auroras Aurora: An aurora is a natural light display in Earth’s sky, usually seen in high-latitude regions. Auroras are caused by charged solar particles interacting with Earth’s magnetic field and atmosphere, producing colorful lights. visible at exceptionally low latitudes, including parts of the United States, Brazil, Europe, and even North Africa.
