Solar Minimum

  • 03 Jul 2020

  • The sun is said to have reached into a state of ‘solar minimum’ as it has been more than 100 days since the sunspots are virtually not visible at all.
  • Solar minimum is the period of least solar activity in the 11-year solar cycle of the Sun. During this time, sunspot and solar flare activity diminishes, and often does not occur for days at a time.
  • It may cause health risks to astronauts travelling through space as the sun’s magnetic field weakens and provides less shielding from these cosmic rays.
