A geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave. The disturbance that drives the magnetic storm may be a solar coronal mass ejection (CME) or (much less severely) a co-rotating interaction region (CIR), a high-speed stream of solar wind originating ...
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 ...
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.
On March 10, 1989, a huge solar flare caused a storm that surged the Quebec power grid, which was out of commission for eight long hours on a weekday morning, affecting about 6 million people.
The solar storm could pose a minimal threat to things ... spirals and flickers that have fascinated humans for millennia. ... the barrier protecting humanity from the harshest effects of space ...
The first visible and electromagnetic effects of a solar flare reach observers on Earth at the speed of light, which means they were spotted about eight minutes after they occurred on the surface ...
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]
ICMEs are capable of reaching and colliding with Earth's magnetosphere, where they can cause geomagnetic storms, aurorae, and in rare cases damage to electrical power grids. The largest recorded geomagnetic perturbation, resulting presumably from a CME, was the solar storm of 1859.
