Abstract
Observations of forbidden line S II λλ6716-6731 A emissions from the Jovian magnetosphere have been carried out with a PEPSIOS spectrometer at the Hale 5 m telescope. Spectral resolving power was sufficient to resolve the forbidden line S II line widths. From measured λλ6716-6731 A doublet ratios and spectral line widths a thermal plasma is found characterized by temperatures about 2 x 10^4 K and electron densities about ~2 x 10^3 cm^(-3). The source of forbidden line S II emissions was centered within a toroidal region of radius 5 Jupiter radii (inside the orbit of Io), with tight latitudinal confinement near the equilibrium equator for ions in the tilted corotating Jovian magnetic field, and significant long-lived longitudinal structure.
