Using currently available observational data, predictions and
prediction uncertainties have been calculated for Solar Cycle 25.
The results, based on both the sunspot number series and observed
magnetic fields, indicate that the upcoming Solar Maximum
(Solar Cycle 25) is expected to be significantly weaker than that
of the current cycle (which near its end). The model results show
that a deep extended solar activity minimum is expected in about
2019-2021, the maximum will occur in 2024 – 2025, and the
sunspot number at the maximum will be about 50 with an error
estimate of ~15-30%. The maximum will likely have a double peak
or show extended high activity over 2 – 2.5-years.
