Space Weather News for May 23, 2021 https://spaceweather.com https://www.spaceweatheralerts.com SOLAR FLARE FRENZY: Yesterday, the sun produced a sequence of solar flares unlike anything we've seen in years. Earth-orbiting satellites detected a dozen explosions in the magnetic canopy of sunspot AR2824. One of them emitted a radio burst so strong, it drowned out static from lightning storms on Earth and was recorded at midnight by listening stations in the Arctic. NOAA forecast models suggest t ...Continue Reading
