A Direct Hit! The impressive #solarstorm launched in the Earth-strike zone has been modeled by NASA. The storm is predicted to hit Earth by midday December 1. Along with two earlier storms already ...
The Sun has unleashed a powerful solar flare, Nasa has said. The flare, designated X2.3, belongs to the most intense X class of flares. It was spotted by Nasa’s Solar Dynamics Observatory, which ...
The extreme ultraviolet and X-ray radiation from solar flares is absorbed by the daylight side of Earth's upper atmosphere, in particular the ionosphere, and does not reach the surface. This absorption can temporarily increase the ionization of the ionosphere which may interfere with short-wave radio communication.
This is the third geomagnetic storm to reach G4 status during the current 11-year solar cycle, which began in 2019, officials said.
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.
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 ...
Radio disruption occurred across North and South America.
The Sun is a G-type main-sequence star (G2V) based on spectral class, and it is informally designated as a yellow dwarf because its visible radiation is most intense in the yellow-green portion of the spectrum. It is actually white, but from the Earth's surface, it appears yellow because of atmospheric scattering of blue light. [9]
