Analysis of the Voyager 2 low-energy charged particle (LECP) and magnetic field (MAG) data in the Uranian magnetotail has shown this system to have many features similar to those seen at Earth. Isotropization of core magnetosphere 28--43 keV ions have been observed at the trapping boundary upon entry into the magnetotail near L=17, an effect seen in ion populations at Earth and attributed to neutral sheet scattering. An extensive and persistent plasma sheet boundary layer was found to contain field-aligned ion streams with a variety of angular and energetically dispersive effects. Streaming distributions in the magnetotail horn region map to the auroral emission region observed by the Voyager ultraviolet spectrometer (UVS). A quiet-time near-tail region is distinguished from a distant disturbed region, where evidence of a substorm is observed. There is evidence suggesting that the distant plasma sheet is not corotating with the planet. Proton density gradients in this disturbed region indicate the presence of detached plasma structures. During what appears to be an occuring substorm, energy dispersionless field-aligned streaming, seen within the neutral sheet region, indicates close proximity to a substormlike acceleration. Extension observations of the Earth's magnetotail provide a model for ordering a variety of particle and magnetic phenomena observed in the Uranian magnetotail. ¿American Geophysical Union 1991 |
