Study Sheds Light on Early Warning Signs Before Eruption of Solar Flares

Gist Researchers using data from India's Aditya-L1 mission have identified small, short-lived brightening events in the Sun's atmosphere that occur hours before major solar flares erupt. These transient events indicate repeated, small-scale releases of magnetic energy that progressively destabilise the solar magnetic field. For civil service aspirants, this is a crucial development in space weather forecasting, as it opens the door to predicting solar flares that can disrupt global communication networks, damage satellites, and threaten astronauts. Background Aditya-L1 is India's first dedicated solar space mission, placed in a halo orbit around the Lagrange point 1 L1 to maintain a continuous, unobstructed view of the Sun. The Sun's atmosphere is composed of several distinct layers: the photosphere the lowest visible surface , the chromosphere the middle layer , and the corona the extremely hot outermost layer . A solar flare is a sudden, intense burst of radiation caused by the rapid release of magnetic energy built up in the solar atmosphere. Historically, predicting exactly when and where a major flare will erupt has been difficult. To accurately forecast these events, scientists…
