Sunspot Cycle
- Recently, scientists from Indian Institute of Science Education and Research (IISER) have developed a way of predicting the intensity of activity in the next solar cycle (approximately from 2020 to 2031).
- Sun-spot cycle:
- The amount of magnetic flux that rises up to the Sun’s surface varies with time in a cycle called the solar cycle which lasts around 11 years on average.
- When flux rises to the maximum, large sunspots appear on the surface of the Sun and become visible.
- Sunspots are regions where the solar magnetic field is very strong. In visible light, sunspots appear darker than their surroundings because they ....
