Four solar flares erupted simultaneously on April 23

Space.com — April 23, 2024, 04:00 PM UTC

Summary: On April 23, the sun emitted four solar flares simultaneously, captured by NASA's Solar Dynamics Observatory. These "super-sympathetic" eruptions involved three sunspots and one magnetic filament, potentially leading to Earth-directed coronal mass ejections. If these impact Earth, they could disrupt power grids, communication networks, satellites, and pose radiation risks to astronauts. The event hints at nearing solar maximum or entering the decay phase of the solar cycle.
