A hidden “switch-off” signal could predict solar storms seven years early

AI Summary

Scientists have discovered a 'switch-off' signal in the Sun's 11-year cycle that can predict solar storms up to seven years in advance. This turning point marks the end of violent space weather in the cycle, aiding improved forecasting of solar activity.

A newly discovered turning point in the Sun’s 11-year cycle could allow scientists to predict future solar activity years earlier than before. At this “switch-off” point, the most violent space weather abruptly ends, and the remaining number of sunspots offers clues about the next cycle’s strength. Early projections suggest Solar Cycle 26 may be moderate, but a clearer forecast is expected in about two years.
