Scientific paper

The flux of magnetic helicity through the solar photosphere has implications in diverse areas of current solar research, including solar dynamo modelling and coronal heating. Other researchers have considered the flux of magnetic helicity from active regions; here, we do the same for quiet-sun magnetic fields. We derive a theoretical expression for the helicity flux in terms of the relative motions of separate flux elements, and the time evolution of the quadrupole moments of individual magnetic flux elements, summing both “mutual” and “self-helicity” contributions to get the total helicity flux. Using a tracking algorithm applied to high cadence, high resolution SOHO/MDI magnetograms, we determine the observed rate of helicity flux in the quiet sun and compare these measurements with our theoretical predictions.
