AB: Reconstructed transverse components of the large-scale solar magnetic field are presented for discussion. To solve an inverse problem of calculating these components, two-decadal time series of the solar photospheric field Synoptic Charts (cortesy of J. T. Hoeksema) of the Wilcox Solar Observatory (years 1976 to 2004) were used. Singular value decomposition technique was chosen for solving the inverse problem. One of the time series shows behaviour of the "radial", or "site-of-view" magnetic field component, another one transversal "North-to-South" solar component. It was revealed, that the low-frequency behaviour of these fields does differ on the time scale chosen (two decades) so does the spatial distribution over the solar surface, while magnitudes of them are comparable with each other. It is supposed that the results would be highly useful for building Sun-Earth connection predictive schemes and for the source surface and solar dynamo models.
