木星十米波辐射的三个参数显然经历着十年周期的周期性变化，它们是幽灵的平均发生概率，主源的中央子午线经度和主源（或源A）的有效宽度。观测结果表明，每个参数的振荡是由木星在绕太阳运行时的视向变化引起的，因此在每种情况下的周期为11.86年。结果表明，在11.86年的时间间隔内，其平均自转周期为9h 55m 29.73s±0.04s。这可能是木星磁场的旋转周期。
Three parameters of Jupiter's decametric radiation which apparently undergo cyclic variations with periods of the order of a decade are the mean occurrence probability for an apparition, the central meridian longitude of the main source, and the effective width of the main source (or Source A). Observational results indicate that the oscillation in each parameter is caused by the apparent change in Jupiter's aspect as it orbits the sun and that the period in each case is therefore 11.86 yr. It was found that the average rotation period over an 11.86 year interval is 9h 55m 29.73s±0.04s. This is probably the rotation period of Jupiter's magnetic field.
