Abstract

Long-slit CCD spectra of the impact parallel of Jupiter were obtained on July 20–21, 1994. Observations were made at Nasmith focus of the 2.6 m Shajn telescope of the Crimean Astrophysical Observatory. Observed spectra covered 4600–10,250 Å at a resolution of 4.5 Å.

Combined investigations of the Nasmith spectra, both the spatial profiles for different spectral regions and extracted spectra for different sites of the crash latitude, show that the impact spots have some spectral peculiarities. Detectable absorption in the observed wavelength region is the general peculiarity of the observed impact sites, except for CH4 bands at 8900 Å and 1 μm, where methane absorption was weakened. Also, our analysis evidenced that there are two types of the spectral peculiarities. One of them, related to the great spots D + G + R + S, K, and L, shows that the absorption in the impact sites is increasing gradually to the blue with respect to the unaffected sites. The other, related to the medium-sized spots, H and N, shows no obvious changes in the gradient of the spots' spectra over a wide wavelength region, except that for the green region, where absorption is slightly weakened.
