The Primary Results of Research on Solar Oscillations by Using Magnetic Field Telescope

The lime series data of λ 5324.19 Å velocity field from Magnetic Field Telescope, at Beijing Observatory, have been analysed. Two (l-v) spectrum for zonal modes and sectorial modes were obtained respectively. Five-minute oscillation and the oscillation with period longer than ten minutes exist in both power spectrum. From the power spectrum, we have recognized f mode, p1 modes and p₂ modes with the degree between 10 and 60. Also, both power spectrum indicate the oscillations with period of 48.3 minutes and degree l equal to 12 and 20, they can be classfied into g modes with order n probably equal to 7 and 10 respectively.
