On Saturday, June 1, 2024, the Sun unleashed two powerful solar flares, peaking at 4:48 a.m. and 2:36 p.m. ET. NASA’s Solar Dynamics Observatory, which continuously monitors the Sun, captured stunning images of these events.
Solar flares are intense bursts of energy capable of impacting radio communications, electric power grids, navigation signals, and posing risks to spacecraft and astronauts. The first flare, occurring early in the morning, was classified as an X1.4 flare, while the second, in the afternoon, was classified as an X1.0 flare. The X-class denotes the most powerful flares, with the number indicating the strength within this category.
