Until mid-2014 Solar Cycle 24 was remarkably quiet. Despite the
steadily declining solar flux since mid-2014, the Sun’s large-scale
magnetic field suddenly strengthened late in 2014 reaching its
highest value in more than twenty years . Using these and related
observations, two Naval Research Laboratory researchers, Wang
and Sheehy, predict in their August 2015 article in The Astrophysical
Journal that Solar Cycle 25 may reach an amplitude similar to Solar
Cycle 24.
Until the unexpectedly sudden and strong increase in the Sun’s large-
scale magnetic field, some solar scientists feared that S olar Cycle 25
might achieve a much lower amplitude than Cycle 24. Those fears
might now be put to rest.
