All across the top of this display are decametric radio emissions originating in the auroral regions of Jupiter. The red, yellow, and green wiggles in this display show tremendous variations in the frequency of the radio waves on very short time scales. The situation is further complicated by the presence of five or more bands of emission occurring at different frequencies at the same time. The time scale for the plot is 10 hours, just slightly longer than Jupiter's rotation period. The radio emission features labeled decametric and hectometric radiation which appear as a mixed set of opening and closing parentheses come from Jupiter and are generally thought to be generated as part of the same process which produces auroras on Jupiter.
Strength is represented by color with red being strongest and blue weakest.
The radio frequency increases along the vertical axis of the display from bottom to top and time increases along the horizontal axis from left to right. Contact Send website feedback to the Webmaster .
