Above is a 10 second spectrograph of Jovian Io-B S-bursting extracted from
the 1348 UT minute of a Jupiter storm that occurred February 13, 2008.
The frequency was 21.1 MHz for this recording. The S-bursts appear as vertical
spikes amidst the cosmic background continuum.
Below are spectrographs of the above specimen processed into one second
timeslices.
