Notes. The first column lists Juno’s orbit number. The second and third columns give the approximate average Io longitude for IFP observations by JIRAM in the northern and southern hemispheres, respectively. The fourth and fifth columns provide the same information for UVS observations. The sixth column shows the spacecraft longitude at closest approach. The seventh column indicates the band of the second uplink channel used for radio occultations (the downlink is always in both X and Ka bands, while the other uplink channel is always in X band). The last column gives the Sun-Earth-Probe angle. Longitudes are referenced to System III.
