This observation will be the most complete (ansa to ansa) spatial and feature (two ansae, torus profiles, and Jupiter aurora) data set since early in the prime mission. The EUV Io torus observation continues the morphological study of the Io torus and provide the basis for a long term comparison between prime mission and GMM datasets over 4 years as well as asymmetries between dawn (prime mission) and dusk (GMM) torus ansae. The UVS instrument is turned off pending resolution of the grating encoder mechanism anomaly. ************************** W.
