FLUX AND IMAGES OF JUPITER AT 13, 22 AND 36 CM BEFORE, DURING AND AFTER SL-9 IMPACTS

Two radio telescopes in Australia, the Australia Telescope and the Mol onglo Observatory Synthesis Telescope were used to observe Jupiter bef ore, during and after the impacts of comet Shoemaker-Levy 9 in July 19 94. The telescopes observed at wavelengths of 13, 22 and 36 cm and pro duced 2-D images of Jupiter's synchrotron radiation belts, showing tha t the brightness of a portion of these belts was strongly affected by the comet impacts. Starting about one day after the first impact and r eaching a peak soon after the time of the last impact the integrated f lux density increased by approximately 25-30% at 13 and 22 cm and 40% at 36 cm.
