Comment on “Observation of long-duration gyroharmonic resonances: A refutation of the short-duration explanation for interpreting the anomalous URAP sounder spectra observed in the Io torus” by P. Canu

Canu [2001] presented observations from the GEOS 1, GEOS 2, and ISEE 1 relaxation sounders to argue against the conclusions of Benson et al. [1997] pertaining to the interpretation of the plasma resonances stimulated by the Ulysses Unified Radio and Plasma Wave (URAP) relaxation sounder in Jupiter's Io plasma torus. He also argued that his observations provided support for the interpretation of th...
