先锋六号于1965年12月16日发射进入绕日轨道，并于1968年11月下旬被太阳遮挡。在航天器被日冕遮挡期间，S波段遥测载体由于这种各向异性等离子体而发生法拉第旋转。加利福尼亚州巴斯托深空网络的 NASA 喷气推进实验室 210 英尺（64 米）天线配备了自动偏振跟踪系统，用于测量这种效应。观察到三种大规模瞬态现象。对这些现象的测量表明发生了大约 40 度的法拉第旋转。每个现象的持续时间约为2小时。这些现象似乎与十度区域波长的太阳射电爆发的观测有关。
Pioneer 6, which was launched into orbit around the sun on 16 December 1965, was occulted by the sun in the last half of November 1968. During the period in which the spacecraft was occulted by the solar corona, the S-band telemetry carrier underwent Faraday rotation as a result of this anisotropic plasma. The NASA-Jet Propulsion Laboratory 210-foot (64-meter) antenna of the Deep Space Network at Barstow, California, which was equipped with an automatic polarization tracking system, was used to measure this effect. Three large-scale transient phenomena were observed. The measurement of these phenomena indicated that Faraday rotation on the order of 40 degrees occurred. The duration of each phenomenon was approximately 2 hours. These phenomena appear to be correlated with observations of solar radio bursts with wavelengths in the dekametric region.
