Post-eruptive loops in the wake of a solar flare, image taken by the TRACE satellite (photo by NASA). In solar physics, a solar particle event (SPE), also known as a solar energetic particle event or solar radiation storm, [a] [1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in ...
Intense solar storms may also be hazardous to high-latitude, high-altitude aviation [7] and to human spaceflight. [8] Geomagnetic storms are the cause of aurora . [ 9 ] The most significant known solar storm, across the most parameters, occurred in September 1859 and is known as the " Carrington event ". [ 10 ]
Geomagnetic storms can have an impact on infrastructure in near-Earth orbit and on Earth’s surface, potentially disrupting communications, the electric power grid, navigation, radio and ...
Solar energetic particles (SEP) accelerated by coronal mass ejections or solar flares can trigger solar particle events, a critical driver of human impact space weather, as they can damage electronics onboard spacecraft (e.g. Galaxy 15 failure), and threaten the lives of astronauts, as well as increase radiation hazards to high-altitude, high ...
A "severe" solar storm could make the northern lights visible in the U.S. farther south than usual while also posing the potential to disrupt modern technology, according to the National Oceanic ...
The incoming solar storm arose from a strong flare near “Region 3500” on the Sun, scientists say. Solar storms are known to interfere with the Earth’s magnetic field and cause damages to ...
The solar storms of May 2024 (also known as 2024 Mother's Day solar storm [1] or Gannon storm in memory of Jennifer Gannon, [2] a space weather physicist [3]) were a series of powerful solar storms with extreme solar flares and geomagnetic storm components that occurred from 10–13 May 2024 during solar cycle 25. The geomagnetic storm was the ...
The sun produced its biggest flare in nearly a decade Tuesday, just days after severe solar storms pummeled Earth and created dazzling northern lights in unaccustomed places. “Not done yet ...
