August 23 , 2024 11 hrs 0 min 18 0
  • Astronomers from the Indian Institute of Astrophysics (IIA) have found a new method to predict the amplitude of the upcoming solar cycle.
  • The astronomers have discovered a new correlation using 100 years of solar data from the IIA’s Kodaikanal Solar Observatory.
  • Space weather is concerned with the varying conditions within the solar system and its heliosphere influenced by the sun and solar wind.
  • The main components of space weather are the solar wind, coronal mass ejections, and solar flares.
  • They discovered that the width of the supergranular cells on the solar surface during the minimum year of the solar cycle is related to the number of sunspots seen during the subsequent solar cycle maximum.
  • This simple method can be used in space weather forecasting.
