Abstract:

Studies of the gross spectrum of the Jupiter radiation now extend all the way from 5 to 31 mc. Indications are that the frequency of occurrence peaks quite sharply near 18 mc and falls off rapidly towards higher frequencies. There is someindication of a secondary maxim m in the low-frequenc region, perhaps near 10 mc. There is also a strong suggestion that the over-all frequency of occurrence of the radiation is inversely correlated with sunspot number. Dynamic spectra obtained with the swept-frequency receiver show that individual pulses of Jupiter radiation h ch normally last from 0.2 to 2 secs. have bandwidths ranging from about 0.3 t 2 mc. There is also strong evi ence that many of these bursts show a fine structure, resembling harmonics spaced from 0.1 to 0.5 mc apart. Author
