The research team predicts that sunspot cycle 25 will be the strongest yet, with between 210 and 260
In the last, 24th cycle, there were 116 spots.A consensus forecast from a group of experts convened by the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA) predicted that the next cycle would be similarly weak, with an estimated 115 sunspots.
However, a new forecast prepared by NCARgoes against conventional wisdom. If confirmed, it would be one of the main pieces of evidence for the unpopular theory that the Sun operates in 22-year magnetic cycles that interact to create secondary activity every 11 years.
According to the study authors, 22-year cyclesare repetitive and can be the key to ultimately accurately predicting the timing and nature of sunspot cycles, as well as the many effects they produce.
The study was supported by the National Science Foundation, which is a sponsor of NCAR and NASA's Living with a Star program.
