太阳风中的电场，在一个赫兹的范围内，首次报道了从一个三轴稳定的航天器。测量是通过卡西尼号航天器上的无线电和等离子体波系统（RPWS）实验完成的[Gurnett et al., 2000]。Kellogg[2000]认为，这种波在维持太阳风离子的近各向同性和MHD描述太阳风的有效性方面可能很重要。发现的振幅比凯洛格从其他测量中估计的要大，并且是由于准静电波。这些振幅足以维持太阳风离子的各向同性。
Electric fields in the solar wind, in the range of one Hertz, are reported for the first time from a 3‐axis stabilized spacecraft. The measurements are made with the Radio and Plasma Wave System (RPWS) experiment on the Cassini spacecraft [Gurnett et al., 2000]. Kellogg [2000] suggested that such waves could be important in maintaining the near‐isotropy of solar wind ions and the validity of MHD for the description of the solar wind. The amplitudes found are larger than those estimated by Kellogg from other measurements, and are due to quasi‐electrostatic waves. These amplitudes are quite sufficient to maintain isotropy of the solar wind ions.
