Solar Flares: A Stormy Sun
May 2024: A Week of Solar Fireworks
The Sun has been putting on quite a show this week, emitting a series of powerful solar flares. These flares, which are sudden bursts of energy, can have a range of effects on Earth, from disrupting radio communications to causing power outages.
The First Flares
The first major flare of the week occurred on May 5, 2024, at 2:01 AM ET. This flare was classified as an X10 flare, the strongest type of solar flare. A second X10 flare followed just hours later, at 10:35 AM ET.
These two flares were the most powerful solar flares in over a decade. They caused widespread radio blackouts and disrupted power grids in several countries.
The Radio Blackouts
The radio blackouts caused by the solar flares disrupted communications for both commercial and military users. Aircraft and ships were unable to communicate with ground control, and some areas even lost power.
The blackouts were particularly severe in the polar regions, where they disrupted auroral viewing and caused problems for scientists studying the aurora borealis.
The Power Outages
The power outages caused by the solar flares were less widespread than the radio blackouts, but they still affected millions of people.
The power outages were caused by the surges of electricity that can occur when a solar flare interacts with the Earth's magnetic field. These surges can damage transformers and other electrical equipment, leading to power outages.
The Geomagnetic Storm Warning
The solar flares have also prompted space weather experts to issue a geomagnetic storm warning for northern latitudes.
A geomagnetic storm is a disturbance of the Earth's magnetic field caused by a solar flare. These storms can disrupt power grids, communications, and other systems.
The geomagnetic storm warning is currently in effect for May 5-9, 2024. During this time, people in northern latitudes may experience problems with electronic devices and power outages.
