The sun produced its strongest solar flare of 2025, an X5. 1-class eruption from sunspot AR4274 triggering severe radio disruptions across continents. The flare—a powerful burst of radiation—was among the strongest in the sun's current activity cycle, researchers say. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event. Minor to active solar storms (i., storming restricted to higher latitudes) may occur under elevated. Coronal mass ejections, or CMEs, are immense clouds of solar material blasted into space by the Sun at over a million miles per hour, often following a solar flare. You can zoom in on this plot by selecting a time period that you wish to view and even export the graph as a JPG, PDF, SVG or PNG file. Beneath that we have a collection of live imagery which.
