Io-B (S&L bursts)

Dynamic spectrum of Jovian Io-B decametric radio emission recorded on September 6, 1997 at 4h 33m 40s UT. Two bands of emissions are present. The low frequency band consists of S bursts; the high frequency band consists of narrow band Lbursts. The horizontal lines at around 27 MHz are Citizens Band (CB) radio stations.


Io-B (N Emission)

Dynamic spectrum of Jovian Io-B decametric radio emission recorded on September 6, 1997 at 3h 31m 50s UT. The emission, drifting slowly between 20 and 22 MHz, is known as N (narrow band) emission. The horizontal lines around 27 MHz are Citizens Band (CB) radio stations. The Jovian emission is almost pure RH circularly polarized.


Io-B (L burst 1)
 
 

Dynamic spectrum of Jovian Io-B decametric radio emission recorded on June 20, 1997 at 10h 12m 50s UT. The emission, consisting of Lbursts, occurs in the frequency range between 17 and 27 MHz. Structures drifting from high to low frequencies at about 40kHz/sec are present. No modulation lanes appear to be present. The emission is RH elliptically polarized. The faint horizontal line at about 27 MHz is radio station interference. 


Io-B (L burst 2)

Dynamic spectrum of Jovian Io-B decametric radio emission recorded on June 9, 1998 at 11h 12m 50s UT. The emission consisting of L Bursts, occurs in the frequency range between 20 to 31 MHz Two sets of drifting features are present. The low frequency features a drift at about 180 kHz/sec; the high frequency drifts at about 60 kHz/sec. The emission is RH elliptically polarized. The diagonal deflection is a sweeper station. Horizontal lines at a constant frequency are radio station interference.
