Solar Flare 2025 What Will Happen. As sunspots and flares, signs of a new solar cycle, bubble from the sun’s surface, scientists are anticipating a flurry of solar activity over the next few years. Solar flares are seen as bright areas on the sun — they're an intense burst of radiation, linked to magnetic energy associated with sunspots.

Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts. This period of elevated activity can last up to several years, with impactful space weather events possible in 2024.
