Full-disk observations of solar oscillations from the geographic South Pole: Latest results

The authors present the latest results obtained from the analysis of the full-disk Doppler shift observations obtained at the geographic South Pole in 1981. Approximately 80 normal modes of oscillation (l = 0-3) have been identified. Their frequencies range from 1886 mu Hz (l = 1, n = 12) to 5074.5...

Description
Summary:The authors present the latest results obtained from the analysis of the full-disk Doppler shift observations obtained at the geographic South Pole in 1981. Approximately 80 normal modes of oscillation (l = 0-3) have been identified. Their frequencies range from 1886 mu Hz (l = 1, n = 12) to 5074.5 mu Hz (l = 2, n = 35), and their amplitudes are as low as 2.5 cm sec super(-) super(1) . Amplitude modulation occurs with periods of 1-2 days, and the individual oscillations appear to be excited randomly and independently. In cases where other groups have observed some of the modes identified by the authors, the agreement in frequency is good.
