Full-disk magnetic oscillations in the solar photosphere

Photospheric observations of the magnetic oscillations have been carried out to research magneto-acoustic waves in
spots. The coupling between the magnetic field and the p-modes has been studied using reduced areas on the solar disk, but
a global scenario is still missing. Four hour full-disk magnetograms (at 4 arcsec/pix spatial resolution) obtained in the sodium D-lines were analysed pixel-by-pixel (locally) and using the spherical harmonics decomposition (globally).
Magnetic oscillations were detected at different frequencies and identified on the solar disk. The global properties of the magnetic oscillations, shown via the elle - nu diagrams, are for the first time presented and discussed.
