Abstract:	Even-order a-coefficients show changes that are correlated with solar activity. We analyze Michelson Doppler Imager (MDI) data that are available for solar cycle 23 to try and determine the change in solar magnetic fields, particularly in the upper part of the convection zone. This is the region where the even-order a-coefficients show the largest change. We use a forward calculation to determine the change in the magnetic fields between the last solar minimum and solar maximum.
