Some decametric radio emissions from Jupiter observed recently exhibit effects which are attributable to Faraday rotation within the earth's ionosphere. We present the evidence for the presence of Faraday rotation and discuss its origin. Identification of the magnetoionic mode in which the emission is generated at Jupiter appears possible, although near the limit of accuracy of our present observations. The emission seems to be generated in the extraordinary mode.
