Jupiter displays many distinct auroral structures, among which auroral dawn storms and auroral injections are often observed contemporaneously. However, it is unclear if the contemporaneous nature of the observations is a coincidence or part of an underlying physical connection. We show six clear examples from a recent Hubble Space Telescope campaign (GO‐14634) that each display both auroral dawn storms and auroral injection signatures. We found that these conjugate phenomena could exist during intervals of either relatively low or high auroral activity, as evidenced by the varied levels of total auroral power. In situ observations of the magnetosphere by Juno show a strong magnetic reconnection event inside of 45 Jupiter radii (R_J) on the predawn sector, followed by two dipolarization events within the following 2 hr, coincident with the auroral dawn storm and auroral injection event. We therefore suggest that the auroral dawn storm is the manifestation of magnetic reconnection in the dawnside magnetosphere. The dipolarization region is mapped to the auroral injection, strongly suggesting that this was associated with the auroral injection. Since magnetic reconnection and dipolarization are physically connected, we therefore suggest that the often‐conjugate auroral dawn storm and auroral injection events are also physically connected consequences.

重新连接和双极化驱动的极光黎明风暴和注入

木星表现出许多不同的极光结构，其中极光暴风雨和极光注入经常同时发生。但是，尚不清楚观测的同时性是巧合还是潜在物理联系的一部分。我们展示了来自最近的哈勃太空望远镜运动（GO-14634）的六个清晰示例，每个示例都同时显示了极光黎明风暴和极光注入特征。我们发现这些共轭现象可能存在于相对较低或较高极光活动的时间间隔内，这由总极光能力的不同水平所证明。朱诺对磁层的原位观测显示在木星半径45（R _J）在黎明前的部分，随后在接下来的2小时内发生两次极化事件，与极光黎明风暴和极光注入事件同时发生。因此，我们认为极光黎明风暴是黎明时磁层中磁重联的体现。双极化区域映射到极光注射，强烈暗示这与极光注射有关。由于磁重联和偶极极化是物理连接的，因此我们建议经常共轭的极光黎明风暴和极光注入事件也是物理连接的结果。
