18?3 Mc/s Radiation from Jupiter

Abstract

Burke and Franklin's discovery of radio emission from Jupiter has been confirmed. Examination of old records has shown that in 1950?51 the radiation came in groups of bursts of very high intensity. Bursts have durations of the order of a minute or less; groups, of an hour. Because of the remarkably close relation between active periods and the period of rotation of Jupiter, it is inferred that the source at the time was very localized. Its identification with a visual disturbance in the South Temperate Belt is very probable.
