LIMITS ON DECAMETRIC RADIATION FROM THE SHOEMAKER-LEVY-9 IMPACTS ON JUPITER

Observations were carried out from South Africa (lat. = -25 degrees.89 , long. = 27 degrees.69) of the collisions of fragments A, E, H, Q1, Q 2, and S with Jupiter. The excellent observing location and winter ion osphere allowed observations at important low frequencies not routinel y accessible at other sites. Observations were carried out at 7.06, 8. 7, 10.2, and 11.9 MHz, and in the entire band 12.4-34 MHz. No signals which could definitely be attributed to the collisions were seen. Sign ificant upper limits on the emissions, depending on frequency and on t he observing conditions during the particular impact, were obtained.
