The Juno spacecraft has made observations related to the moon Callisto and its effect on Jupiter's aurorae. However, reports vary, with some focusing on Callisto's ultraviolet footprint, while others discuss the auroral signatures of Jupiter's other large moons, including Ganymede, Io, and Europa. The observations appear to be part of a broader effort to understand Jupiter's aurorae and the interactions between the planet and its moons.
