Magnetism of the Quiet Sun

Although historically we have used the term Quiet Sun with the
thought that outside of active regions there is little interesting
happening, the opposite is the case. Away from active regions new
magnetic flux is constantly emerging. This new flux is responsible for
the mixed polarity seen over the entire solar disk. The constant
emergence of magnetic flux replaces the Quiet Sun field in less than a
day and even the active region flux in less than a month. There is
increasing evidence that this flux is the result of dynamo action
occurring on the scales of the flux emergence rather than reprocessing
of the active region flux. It is now been appreciated that statistical
fluctuations and scale mixing of magnetic structures allows energy
transport and energy conversions of scales much larger than the scales
of magnetic flux emergence.
