Weblines on the 720-km surface, we can study the magnetic conjugate property of this large density irregularity structure at many points along the FS-5 orbit. We shall use the Hilbert-Huang Transform (HHT) to analyze the density variations on either side of the dip equator for the large- and small-scale density irregularity structure.
