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 ...
A solar storm is a disturbance on the Sun, which can emanate outward across the heliosphere, affecting the entire Solar System, including Earth and its magnetosphere, and is the cause of space weather in the short-term with long-term patterns comprising space climate.
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 radiation from these flares travel at the speed of light. Some reached Earth, causing some minor radio signal blackouts over the last couple of days. ... If this week's solar storm hits at a ...
An unusually strong solar storm hitting Earth produced stunning displays of color in the skies across the Northern Hemisphere early Saturday, with no immediate reports of disruptions to power and ...
A severe solar storm is expected ... will help forecasters measure the solar wind and understand the timing and potential effects more precisely. ... this geomagnetic and solar radiation can ...
An extreme storm, estimated at Dst −531 nT arose from a fast CME (mean ≈1500 km/s), occurred during the ascending phase of the minimum of the relatively weak solar cycle 14, which is the most significant storm on record in a solar minimum period. Aurora was conservatively observed to ≈44.1° ILAT, and widespread disruptions and ...
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 ...
