Solar Cycles

Solar Cycles Latest News

Recently, the IIT-Kanpur team developed a new way to predict solar cycles.

About Solar Cycles

• The solar cycle describes an approximately 11-year cycle of solar activity driven by the sun’s magnetic field.
• It is indicated by the frequency and intensity of sunspots visible on the surface. 
• Every 11 years or so, the Sun’s magnetic field completely flips.
• This means that the Sun’s north and south poles switch places. Then it takes about another 11 years for the Sun’s north and south poles to flip back again.
• The solar cycle affects activity on the surface of the Sun, such as sunspots, which are caused by the Sun’s magnetic fields.
• As the magnetic fields change, so does the amount of activity on the Sun’s surface.
• It can be tracked by counting the number of sunspots.
• Cycle Stages

• • Solar minimum: It is the beginning of a solar cycle or when the Sun has the least sunspots.
    • Over time, solar activity—and the number of sunspots—increases.
  • Solar maximum: It is the middle of the solar cycle or when the Sun has the most sunspots.
    • As the cycle ends, it fades back to the solar minimum, and then a new cycle begins.
• Impact: The solar cycle has the potential to impact Earth’s climatic conditions through changes in solar radiation, cosmic rays, and ozone distribution.
