Monitoring Jupiter's hectometric emission

Abstract

The feasibility of long-term monitoring of the Jovian hectometric radiation component (nominal range between 0.3 to 3 MHz) is considered. It is recommended that long-term monitoring of Jupiter at frequencies around 1 MHz should be conducted either from a high-orbit earth satellite or from the surface of the moon. Such a program would eventually provide a record of rotation period changes revealing secular variations in the Jovian magnetic field, with a sensitivity much higher than could be achieved from the earth.
