All indications are that the upcoming solar minimum which is expected to begin in 2019 may be even quieter than the last one which was the deepest in nearly a century.
Some scientists are even saying that we are on the cusp of a new grand solar minimum, and the upcoming cycle 25 may have even lower cycles after it.
This empirical modeling of solar recurrent patterns has also provided a consequent multi-millennial-scale experimental forecast, suggesting a solar decreasing trend toward Grand (Super) Minimum conditions for the upcoming period, AD2050–2250 (AD 3750–4450).
