美国国家航空航天局朱诺号任务上的木星极光分布实验离子传感器（JADE‐I）在航天器到达木星前约40天测量了太阳风离子，同时进行了大量的木星极光望远镜观测。JADE - 1是一种热等离子体飞行时间仪器，用于测量木星的极光和磁层离子。本研究提供了接近阶段的太阳风参数数据集，可用于与木星极光的远程测量相协调的研究，与从地球传播太阳风条件的模型进行比较，并适用于木星弓形激波或磁层顶模型。虽然在朱诺号接近过程中预测了多次弓形激波交叉，但只有一次观测表明，随着朱诺号接近，压缩磁层正在缩小。然而，船首激波处计算的撞击压力接近这40天的中位数，而不是处于较高的百分位数。
The Jovian Auroral Distributions Experiment ion sensor (JADE‐I) on board the National Aeronautics and Space Administration's Juno mission measured solar wind ions for ≈40 days prior to the spacecraft's arrival at Jupiter, simultaneous with numerous telescope observations of the Jovian aurora. JADE‐I is a thermal plasma time‐of‐flight instrument designed to measure Jovian auroral and magnetospheric ions. This study provides a solar wind parameter data set for the approach phase that may be used in coordinated studies with remote measurements of the Jovian aurora, to compare with models that propagate solar wind conditions from Earth and to apply to Jovian bow shock or magnetopause models. While multiple bow shock crossings were predicted during Juno's approach, there was only one observed suggesting a compressed magnetosphere that was shrinking as Juno approached. However, the calculated ram pressure at the bow shock was near the median value of those 40 days, rather than being in an upper percentile.
