  • Sun activity for September 13, 2023: Unexpected geomagnetic storm last night. Aurora alert!

    Posted by C. Alex Young and Raúl Cortés and Armando Caussade, September 13, 2023 An unexpected coronal mass ejection (CME) hit Earth’s magnetic field last night and caused a G1 (minor) geomagnetic storm, which then intensified to a G2 (moderate) storm. The CME was likely fired into space after a filament eruption on September 8–9, and eventually collided with Earth on…

  • How dangerous are solar storms really?

    In “The Superflare”, an eruption on the sun triggers an EMP, destroying all digitized devices and power grids worldwide – a disaster for the fully digitized world in 2051 and the starting point for the novel’s plot. But are we also threatened by such a danger? Or would a solar storm end similarly mildly as…

  • Threat of the Sun and Superflare

    By Kazunari Shibata, Kwasan and Hida observatories, Kyoto University, March 11, 2016 Magnetic storm and aurora on 1989 March 13, that lead to Quebeck blackout Will the Carrington class flare occur again? Can much bigger flares, superflares (>10^33 erg) occur on the Sun at present? What is the impact of superflares on the earth, if…

  • How a Rare Solar ‘Superflare’ Could Cripple Humanity

    By Robert Roy Britt – Jun 20, 2019 Our networked, electrified society makes us uniquely vulnerable to the effects of sudden solar weather ·

  • Rare ‘superflares’ could one day threaten Earth

    June 10, 2019 • By Daniel Strain Now, new research shows with more confidence than ever before that superflares can occur on older, quieter stars like our own—albeit more rarely, or about once every few thousand years. The results should be a wake-up call for life on our planet, said Yuta Notsu, the lead author of the study and a…

  • Could a superflare happen on our sun?

    In recent years, astronomers probing the edges of the Milky Way have observed very strong explosions on stars, which they’ve dubbed “superflares,” that have energies up to 10,000 times that of typical solar flares. (…) Now, new research suggests superflares can also occur on older, quieter stars like our own sun, albeit more rarely, perhaps once…

  • What are the chances of a hazardous solar superflare?

    By Stephen Battersby, November 19, 2019 On March 1, 2010, the Kepler space telescope spotted a distant star brighten slightly. Compared with the ferocious intensity of a supernova or gamma-ray burst, this event was feeble. It was merely a stellar flare, and by no means the most powerful flare ever seen. Nevertheless, it was ominous.…

  • When is the sun’s next ‘Superflare’ due?

    Last bombardment exploded telegraph wires, pushed Northern Lights south In 1859, a massive solar flare bombarded Earth with so much energy that telegraph wires burst into flames, and stunning auroras could be seen as far south as Cuba and Hawaii. Such a powerful event would likely be devastating for our modern world, with the potential…
