Left Panel. Juno pierced Ganymede's magnetosphere, moving from the left to the right, at times indicated on the red trajectory line. Ganymede's closed field lines are shown in green, with open field lines connecting Ganymede to Jupiter in blue. Jovian field lines not connected to Ganymede, black, are distorted by the presence of the Ganymede field (Duling et al., 2022). Right panel. Juno's trajectory shown in the Cartesian GPhiO coordinates defined as: the primary axis $\hat{Z}$ is parallel to Jupiter's rotation axis in the northward sense, the secondary axis $\hat{Y}$ is along the Ganymede‐Jupiter direction, and the $\hat{X}$ axis completing the right‐handed coordinate system and in the plasma corotation direction; Ganymede's radius (R _G) = 2631.2 km.
