| Description: | At low frequencies (< 40MHz), Jupiter is sometimes the brightest source in the sky. The Jupiter/Io magnetosphere produces its most intense radio emission by the cyclotron maser process. LOFAR/CS1 observed this emission at high-time resolution in a coordinated campaign with the Nancay Decametric Array. The first plot shows the dynamic spectrum for this observation over two minutes of strong emission. Although there is some interference (vertical stripes), the somewhat broader, wavy emission from Jupiter is easily visible. The second plot shows a dynamic spectrum for 0.2 seconds, which demonstrates the complex structure in the emission. |
