Solar Activity Impacts Earth's Magnetic Field

Powerful magnetic forces tangled
in the solar wind, fracture and shatter
then rejoin with vengeance till flares, mangled
and twisted in bits of stellar matter,
pop-off on the solar surface. It’s jazz
played with frenzied brutality. It’s twitching
epileptically toward the poles. Viewed as
dynamic motions, it keeps enriching
catastrophic solar events. The sun
is miasmic. It is a complex beast.
It churns and quivers. It stops for no one.
A ball of hydrogen, to say the least!
Fluids ebb and flow on a disc shaped star,
materials suddenly fling out far.

************************

 The Sun is a seething ball of ionized gas, called plasma, and has very complex magnetic fields that interact with this plasma.  The Solar activity impacts the magnetic fields of the Earth. It also has significant influence on Earth’s weather.
