Io -A (L burst)
Dynamic spectrum of Jovian Io-A decametric radio emission recorded on August 9, 1998 at 8h 36m 20s UT. The emission consisting of L Bursts shows a complex structure. The intensity of the bursts is modulated by irregular-shaped structures drifting from high to low frequencies. The emission is almost pure RH circularly polarized. Horizontal lines at a constant frequency are radio station interference.
