We examine the relationship between the change of helioseismic frequencies at high latitudes during the solar cycle and the change in the solar polar magnetic field. Helioseismic data from SOHO/MDI are used to construct a helioseismic butterfly diagram, that is, the total contributions, binned by latitude, of the p-mode splittings decomposed into Legendre polynomials. We cover the period of the rise of Cycle 23. We compare the frequency change contributions to polar field strengths, in latitude bins, obtained from BBSO polar field observations. Also we examine the residual intensity variations, binned by latitude from the BBSO solar disk photometer.
