Simultaneous Extreme Ultraviolet and Far Ultraviolet Observations of Jupiter Aurora by Galileo Orbiter
In 1996 during the first four orbits of the satellite tour the Galileo Ultraviolet Spectrometer (UVS) (1100-4300 Angstroms) and Extreme Ultraviolet Spectrometer (EUVS) (550-1300 Angstroms) performed near-simultaneous observations of the Jupiter aurora in both the north and south polar regions.

High Resolution UV Emission Cross Section for Analysis of Satellite Observations of Aurora and Dayglow of Planetary Atmosphere
A new generation of high resolution UV imaging spacecraft (Polar, Galileo, HST) are studying the airglow and aurora of the Earth and the Jovian planets. To keep pace with these technological improvements we have developed a laboratory program to provide electron collision cross sections of the major molecular planetary gases (H (sub 2) , H, O, N (sub 2) , CO (sub 2) , SO (sub 2) , O (sub 2) , H (sub 2) O, and CO).

WFPC2 Imaging of Saturn's Far-Ultraviolet Aurora
This oral report describes the first images of Saturn's far- ultraviolet polar aurora taken with the Hubble Space Telescope Wide Field and Planetary Camera 2 in October 1994. The images revealed auroral emissions from atomic and molecular hydrogen in both the north and south circumpolar region. Details of this observational data are given and interpreted.

Scale Size-Dependent Characteristics of the Nightside Aurora
We have determined the spatiotemporal characteristics of the magnetosphere-ionosphere (M-I) coupling using auroral imaging. Observations at fixed positions for an extended period of time are provided by a ground-based all-sky imager measuring the 557.7 nanometer auroral emissions. We report on a single event of nightside aurora (at approximately 22 magnetic local time) preceding a substorm onset. To determine the spatiotemporal characteristics, we perform an innovative analysis of an all-sky imager movie (19 minutes duration, images at 3.31 hertz) that combines a two-dimensional spatial fast Fourier transform with a temporal correlation. We find a scale size-dependent variability where the largest scale sizes are stable on timescales of minutes while the small scale sizes are more variable. When comparing two smaller time intervals of different types of auroral displays, we find a variation in their characteristics. The characteristics averaged over the event are in remarkable agreement with the spatiotemporal characteristics of the nightside field-aligned currents during moderately disturbed times. Thus, two different electrodynamical parameters of the M-I coupling show similar behavior. This gives independent support to the claim of a system behavior that uses repeatable solutions to transfer energy and momentum from the magnetosphere to the ionosphere.
