MULTIWAVELENGTH RADIO OBSERVATIONS OF THE ENCOUNTER BETWEEN JUPITER AND COMET SHOEMAKER-LEVY-9

We present the results of radio continuum observations of the Jupiter - Comet Shoemaker-Levy 9 encounter, carried out at 3.6 cm, 6 cm, 74 cm with the two 32 m antennas located in Medicina and Note (Italy) and w ith the Northern Cross Interferometer (Bologna, Italy). Additional obs ervations at 11.7 m are also presented. In agreement with the results obtained by other groups, our data show that Jupiter synchrotron flux increased considerably as a consequence of the impacts, the flux varia tions increasing with decreasing radio wavelength.
