Modulated spectral activity (MSA) - Implications for planetary radio sourcesThe properties of the Jovian and Saturnian MSA, modulation patterns within the normally diffuse nonthermal radio emission that are characterized by distinctive banded structures of enhanced intensity fluctuations in frequency over time scales of minutes to tens of minutes, are discussed. Although Jovian and Saturnian MSA are both normally observed in the 0.2-1.3-MHz frequency range, similar pattern have been noted in Jovian decametric emission above 30 MHz. The MSA properties are used to constrain the possible source mechanism.
