Scientific paper

The origin of the solar oscillations and the interaction with the magnetic field are usually considered as two distinct problems. Four hours of 1 minute cadence full-disk dopplergrams, longitudinal magnetograms and intensity images, taken in the sodium D lines at Kanzelhöhe Solar Observatory, have been analyzed to investigate possible spatial correlations between the magnetic oscillations and the Hα bright points. The phase relation between the velocity and intensity images is used to enhance the magnetic signatures in the low spatial resolution images. The coincidences between the magnetic oscillations locations and the Hα bright points suggest to investigate the magnetic reconnections as a possible source of solar oscillations.
