Notes

  • A study by researchers from Manipal Centre for Natural Sciences, Manipal Academy of Higher Education, ISRO, and other academicians identified early warning signs of solar flares.
  • The study utilized data from three payloads on the Aditya-L1 mission: Solar Ultraviolet Imaging Telescope (SUIT), Solar Low Energy X-ray Spectrometer (SoLEXS), and High Energy L1 Orbiting X-ray Spectrometer (HEL1OS).
  • Findings indicate that small, short-lived 'transient' brightenings occur in the sun's atmosphere hours before a major solar flare.
  • These transient events cluster around the specific location where the major flare subsequently erupts.
  • The mechanism involves repeated small-scale energy releases that progressively destabilize the magnetic field in an active region, leading to a large flare.
  • SUIT observes the sun in 11 near-ultraviolet (NUV) filters, accessing layers from the upper photosphere to the chromosphere, which are typically blocked by Earth's atmosphere.
  • SoLEXS and HEL1OS measure X-ray emissions from the solar corona, allowing researchers to link lower solar atmosphere activity to coronal energy release.
  • Improved flare forecasting is critical for protecting satellites, communication systems, and astronauts from space weather events.
