10 de mai. de 2024 · CMEs are explosions of plasma and magnetic fields from the sun’s corona. They cause geomagnetic storms when they are directed at Earth. Geomagnetic storms can impact infrastructure in near-Earth orbit and on Earth’s surface, potentially disrupting communications, the electric power grid, navigation, radio and satellite operations.
Há 6 dias · geomagnetic storm, disturbance of Earth’s upper atmosphere brought on by coronal mass ejections—i.e., large eruptions from the Sun’s outer atmosphere, or corona. The material associated with these eruptions consists primarily of protons and electrons with an energy of a few thousand electron volts .

15 de mai. de 2024 · Historic Geomagnetic Storm Dazzles. The strongest geomagnetic storm in over two decades dazzled scientists and sky-watchers alike in May 2024. The G5 storm culminated in a remarkable display of the aurora borealis overnight on May 10–11, visible from many areas worldwide, including latitudes where sightings of auroras are uncommon.
11 de mai. de 2024 · What is a geomagnetic storm? Geomagnetic storms originate from a specific type of activity taking place on the Sun. Large "clouds" containing billions of tonnes of plasma embedded within an ejected magnetic field erupt from the Sun's outer atmosphere, or corona. These eruptions are known as coronal mass ejections (CMEs). Loading...
16 de mai. de 2024 · Traveling at speeds up to 3 million miles per hour, the CMEs bunched up in waves that reached Earth starting May 10, creating a long-lasting geomagnetic storm that reached a rating of G5—the ...
