Sunspots have been observed for over four centuries and the magnetic nature of sunspot cycles has been known for about a century. However, some of its underlying physics still remain elusive. In new research, astronomers at IISER Kolkata discovered a new relationship between the rise rate of the sunspot cycle and the Sun’s magnetic field. Their results indicate that the maximum intensity of solar cycle 25, the ongoing sunspot cycle, is imminent and likely to occur within a year.
