The International Ultraviolet Explorer observed the Galilean satellites over a decade time span. This data has been examined to determine the rotational phase curve behavior of these satellites from 0.26 to 0.32 microns in 0.01 micron increments. The general behavior of the lightcurves is commensurate with that seen by the Voyager and Galileo observations. The data has been separated into time periods, 10 years apart, to examine possible temporal variations. Preliminary analysis indicates that any temporal variations are only a few percent above the noise level in the data.
