Solar cycle 25

Common card · No. 280756

Solar cycle 25 is the current solar cycle, the 25th since 1755, when extensive recording of solar sunspot activity began. It began in December 2019 with a minimum smoothed sunspot number of 1.8. It is expected to continue until about 2030. While it was initially predicted by most scientists that cycle 25 would be relatively weak, solar activity has been much stronger than the predictions.
