A final reduction has been made of extensive observations of Jupiter conducted during 1961 and 1962 in the radiofrequency range 5-31 Mcs. Both probability-of-emission and intensity studies have been made of the several decametric sources. It appears that a change in the apparent rate of rotation of the sources occurred in 1960. Both the over-all Jovian activity and the apparent widths of the sources have increased as the solar cycle declined, although the gross source geometry remains much the same as in previous years. Television techniques have been used in a search for optical activity correlated with the Jovian outbursts. Venus and Mars have shown no detectable decametric activity, while Saturn remains, as before, a dubious source. Author
