Grün, E., D.P. Hamilton, M. Baguhl, R. Riemann, M. Horanyi and C. Polanskey 1994. Dust streams from comet Shoemaker-Levy 9? Geophys. Res. Let. 21, #11, 1035-1038.


Both in 1991 and 1992, the dust detector onboard the Ulysses spacecraft detected several dust streams within a few thousand radii of Jupiter apparently originating from the jovian system. Both the timing and measured speeds of the two last dust streams detected are compatible with dust from comet Shoemaker-Levy 9's (SL9) disruption in 1992. Our investigations of stream characteristics and dust acceleration mechanisms, however, show that this is an unlikely possibility. In July 1994 when SL9 impacts Jupiter, the Galileo spacecraft will about 3500 jovian radii away from the planet. Submicron-sized dust released into, and accelerated by, the jovian magnetosphere during this event may reach Galileo and be detected by its dust detector between September and November 1994. We also discuss the possibility of directly sampling dust from SL9 during Galileo's orbital tour.
