摘要：
The discrete spectrum of global solar modes was discovered in 1979 by Claverie et al. Here we report the first determination of the continuum spectrum in velocity, where atmospheric and instrumental effects have been significantly reduced. Cross-correlations of velocity measurements at four observing stations of a global network have made this possible. The solar noise power is a factor of 5 lower than expectations.
