On July 11, 2020, NASA’s Parker Solar Probe made its third flyby of Venus. The upper hybrid resonance emission was observed below 1,100 km (a first at Venus), revealing electron densities an order of magnitude lower than at solar maximum. These observations are consistent with a substantial variation in the density and structure of the Venusian ionosphere over the Solar Cycle.

从帕克太阳探针上混合​​共振发射的观测,接近太阳极小值时,金星电离层的血浆离子密度耗尽

2020年7月11日,美国国家航空航天局(NASA)的帕克太阳探测器Parker Solar Probe)第三次飞越金星。在1100 km以下观察到了较高的混合共振发射(金星首次发射),揭示出电子密度比太阳最大值时低一个数量级。这些观察结果与太阳周期金星电离层的密度和结构发生重大变化是一致的。
