Stronger Solar Activity Cycles May Be in the Sun’s Forecast

SMRTR summary

Solar activity is approaching its peak in the current 11-year cycle, producing spectacular auroras visible as far south as Florida. While recent months have seen a slight slowdown in sunspots, scientists are unsure if solar maximum is ending or if another activity spike may occur. Future solar cycles may be even more active than recent decades, with potential impacts on satellites, power grids, and space exploration. Improved space weather forecasting will be crucial as human missions venture beyond Earth orbit.
