JIRAM field of view JIRAM swath UVS swath (mirror position: +10degrees) Juno horizon Terminator UVS field of view (mirror position: +10degrees) “Mean” aurora from Hubble Space Telescope FUV images Juno visibility limit for features at 1000 km altitude Extremity of the UVS field of regard

Juno footprint according to the VIP4 magnetic field model (Connerney et al, 1998) Juno footprint according to the VIPAL magnetic field model (Hess et al, 2011) Sub-Juno position Point where the surface magnetic field and the Juno direction are co- aligned

Extremities of the UVS field of regard Main Oval (MO) in red: The Juno VIPAL footprint is <5000km from the MO (i.e. Juno is close to MF lines connected to the MO) Main Oval (MO) in blue: A portion of the MO is <5000km from the Juno horizon (useful for vertical extension measurements) IFP tail in blue: A portion of the IFP tail is <2000km from the Juno horizon (useful for vertical extension measurements) GFP in blue: The GFP is <5000km from the Juno horizon (useful for vertical extension measurements)
