This dynamic spectrum recorded at the University of Florida Radio Observatory shows the typical time vs. frequency behavior for a series of Jovian L-bursts. Unlike S-bursts, the instantaneous bandwidth of an L-burst is very large, often greater than 5 MHz. L-bursts have a slow undulating quality that reminds many listeners of waves crashing on a distant beach. Note that in this dynamic spectrum the horizontal (time) axis is over 90 seconds long. In the S-burst dynamic spectrum the time axis covers just 160 milliseconds.
L Burst Sounds -- L bursts sound a little like waves crashing on a beach. Do you agree? [RealPlayer format] [*.au format]
