Study using Aditya-L1 data reports pre-flare UV brightenings as potential warning signs

Researchers from the Manipal Centre for Natural Sciences/Manipal Academy of Higher Education and ISRO (with other collaborators) reported that small, short-lived brightenings in the Sun’s atmosphere appear in the hours before major solar flares and cluster near where the flare later occurs. The study used simultaneous ultraviolet and X-ray observations from Aditya-L1 payloads SUIT, SoLEXS and HEL1OS, and found some of the pre-flare transient events had corresponding X-ray signatures consistent with magnetic energy release.
