Solar Radiation Storms: A Threat to Earth

A Large-Scale Magnetic Eruption

Solar radiation storms are caused by a large-scale magnetic eruption on the sun, which often causes a coronal mass ejection and associated solar flare. These storms can have a significant impact on Earth's atmosphere, causing geomagnetic storms that can disrupt power grids, communications, and navigation systems. In extreme cases, solar radiation storms can even pose a threat to human health.

The Carrington Event of 1859

The largest known geomagnetic storm in history occurred in 1859, and is known as the Carrington Event. This storm caused telegraph stations to spark and catch fire, and disrupted communications around the world. The Carrington Event is a reminder of the potential dangers of solar radiation storms, and highlights the need for us to be prepared for future events.

Recent Geomagnetic Storm

On May 10, 2024, a dramatic blast from the sun set off a geomagnetic storm in Earth's atmosphere. The storm is expected to cause minor disruptions to power grids and communications, but is not expected to pose a major threat. The plot on this page shows us the most recent 24-hour solar X-ray data from the primary GOES satellite.
