报告了1954年6月、1955年11月1日至1956年3月13日对木星进行的射电观测。讨论了该计划的三个方面：
(1)观测与木星自转的相关性；
(2) 辐射的偏振；
(3)频率特性。
在观测期间，地球上至少存在三个活动中心，围绕非赤道区域旋转。没有注意到无线电噪声与可见特征的明确相关性。白点 DE 在 1951 年的数据中被认为可能存在相关性，但与 1955-56 年的射电噪声事件绝对没有很好的相关性。最活跃的射电区域表现出9小时55分33秒的自转周期，该值与其他测定结果一致，也与系统III建议的长期自转周期一致。大多数无线电噪声突发都是强圆极化的。对于最活跃的区域，仅观察到右旋圆偏振的爆发。无线电噪声频谱在观察到的频率组上似乎并不连续。卡内基和澳大利亚联合观测结果并不支持窄可见角是木星电离层临界反射证据的假设。
Radio observations of Jupiter made in June 1954 and November 1, 1955, to March 13, 1956, are reported. Three aspects of the program are discussed:
(1) Correlation of observation with the rotation of Jupiter;
(2) Polarization of the radiation;
(3) Frequency characteristics.
During the period of observation, there were at least three centers of activity on the planet, rotating approximately with the non-equatorial regions. No definite correlation of radio noise with visible features was noted. The white spot DE, noted as a possible correlation in 1951 data, was definitely not well correlated with radio noise occurrences in 1955–56. The most active radio region exhibited a rotational period of 9h55m33s, a value consistent with other determinations and also consistent with the suggested long-term rotational period, system III. Most of the radio noise bursts were strongly circularly polarized. For the most active region, only bursts of right circular polarization were observed. The radio noise spectrum does not appear to be continuous over the observed set of frequencies. The hypothesis that the narrow angle of visibility is evidence for critical reflection by the ionosphere of Jupiter is not supported by the combined Carnegie and Australian observations.
