Near-infrared emissions of the SL9 impact sites of Jupiter have been recorded on July 16--18, 1994, at ESO (La Silla, Chile). A very strong emission of methane was recorded between 3.50 and 3.56 &mgr;m, shortly after impact H, showing evidence for a temporary increase of the Jovian stratospheric temperature. Emissions of H2 (2.12 &mgr;m) and H+3 (3.53 &mgr;m) were also detected above some of the impact sites, several hours after the impacts. The observed H+3 emissions, however, seem to be at least partly contaminated by the southern aurora. A strong continuum was also detected at 2.12 &mgr;m over most of the impact sites, presumably due to intense scattering of reflected sunlight by stratospheric haze. ¿ American Geophysical Union 1995
