The sunspot cycle is a cyclical rise and fall of the number of magnetic storms on the sun and is associated with increased and decreased solar radiation received by the earth.

What is the sunspot cycle?

The solar cycle, also known as the sunspot cycle, solar magnetic activity cycle, or Schwabe cycle, is a nearly periodic 11-year fluctuation in the activity of the Sun as determined by changes in the number of sunspots that can be seen on its surface. The lengthier, 22-year cycle of solar activity is really divided in half by the 11-year sunspot cycle. The magnetic field of the Sun associated with sunspots reverses polarity with each increase and decrease in the sunspot count, and the direction of the magnetic fields in the northern and southern hemispheres of the Sun alternates. According to NASA Space Place, the magnetic field of the sun controls the solar cycle. The level of activity on the solar surface is influenced by changes in the magnetic field of the sun.
