observations of the aerosol debris from the collision of SL-9 with
Jupiter: A review from La Palma and Calar Alto imaging and
spectroscopy. In Proceedings of the European SL-9
Workshop, R. West and H. Böhnhardt, Eds., 311-316.
We present results from analysis of imagery and spectra of the effects of
the collision of fragment H of comet Shoemaker-Levy 9 with the Jovian
atmosphere. The images were obtained using several narrow-band filters at
UV trough 2.3 $\mu$m wavelength under excellent seeing conditions. The
large range incidence and emission angles at which the impact site was
recorded allowed us to obtain the physical properties of the debris
particles generated. We found that the particles were confined between 1
and 450 mbar, had a modal radius of 0.15 $\mu$m, and imaginary refractive
index of 0.02 in the UV and 0.006 in the 1 $\mu$m region, in close
agreement with the reported values by West et al. (1995) from Hubble Space
Telescope imagery. The derived lower limit of the impactor size correspond
to the volume of a sphere of 230 m in diameter.
