​Thermal & Magnetic Structure of Solar Coronal Holes

Recently, in a study by the Indian Institute of Astrophysics (IIA), astronomers successfully mapped the thermal and magnetic properties of solar coronal holes, which influence space weather and impact the Indian monsoon.

What are coronal holes and why do they matter?

  • Coronal holes are dark regions in X-ray and ultraviolet images of the Sun, with open magnetic field lines that release high-speed solar winds (450-800 km/s).
  • These solar winds affect satellites, Earth's ionosphere, radio communications, and even contribute to geomagnetic storms.
  • Recent studies suggest that coronal holes influence Indian monsoon variability, making their study crucial.
