The UV range in particular is adequate to measure collisionaly excited transitions of H and H2, the dominant species in the upper atmosphere of giant planets, produced by precipitating auroral particles, and benefits a good angular resolution. Auroral UV observations therefore provide a rich source of informations on planetary atmospheres and magnetospheres. They also offer a unique diagnostic to remotely probe the solar wind activity throughout the heliosphere.apis.epn_coreEpnCore table for APIS serviceivo://ivoa.net/std/epntap#table-2.0granule_uidInternal table row index, which must be unique within the table.
