The biggest geomagnetic storm of 20 years: NASA lessons and surprises
NASA’s Solar Dynamics Observatory took an image of the sun on May 7, 2024 with extreme ultraviolet rays (wavelength of 304ÅNGSTROMS). In the center, the active region that incited the Ganon Storm grows about 17 times larger than the Earth. (Scaled images of the Earth are inserted for size reference.) In early May 2024, the active region released a chain…
