Polar Cap Region

Because of its high-latitude trajectory, Ulysses was able to investigate the poleward extent of Jupiter's radiation belts. A surprising finding was that, even close in to the planet (approximately 9 Jupiter radii), Ulysses apparently made an excursion out of the radiation belts at relatively low magnetic latitudes (48 degrees).
