We mapped the distribution of H3(+) emissions in Jupiter's polar regions utilizing 3.4-micrometer images acquired with ProtoCAM at the NASA IRTF (Infrared Telescope Facility). A sequence of image mosaics was used to constrain the parameters of an emission source model. A generalized inverse methodology, applied to individual pixel intensities in the sequence of auroral images, is used to constrain the model parameters. A combination of the System-3 fixed anomaly (equatorward of the auroral oval) plus the local-time fixed anomaly (poleward) was found to simulate the emission intensities in both aurorae consistently well. Weaker H3(+) emissions are found both poleward and equatorward of the oval, the latter extending approximately to the footprint of the Io torus at most longitudes. System-3 anomalies are tentatively identified at longitudes where the local magnetic field strength is less than that at the conjugate point.
