    Multiscale analysis of active region evolution by Hewett, R, Gallagher, P, McAteer, R, Young, C, Ireland, J, Conlon, P, Maguire, K

    Published 2008
    “…Here, a continuous wavelet technique is developed, analyzed, and used to investigate the multiscale structure of an evolving active region using magnetograms obtained by the Michelson Doppler Imager (MDI) onboard the Solar and Heliospheric Observatory (SOHO). The multiscale structure was measured using a 2D continuous wavelet technique to extract the energy spectrum of the region over the time scale of 13 days. …”
