Lebo, G. R. ; Smith, Alex G. ; Carr, T. D. Abstract A recent publication by Bigg (Nature 203, 1008, 1964) calls attention to an apparent correlation between the longitude of the Jovian satellite Io and the occurrence of decametric emission during the years 1961 and 1962. Computer techniques have been used to search the extensive multifrequency data of the University of Florida Radio Observatory, which go back to 1957. An Io influence seems to appear strongly in 1961 and 1962, but the effect is less marked during the interval 1958-1960. The correlation is also much weaker at the lower frequencies, from S to 15 Mc/sec. It is interesting to note il~at the Io influence is far stronger for analyses that include intensity rather il~an simple probability of occurrence i.e., the satellite appears to produce an amplitude modulation. Analyses are also being carried out for possible effects of the second and third satellites. Preliminary results for the 1962 apparition indicate that these bodies may also produce a detectable amplitude modulation.
