IRTF Images of Fragment A Impact


These images show thermal infrared radiation from Jupiter at different wavelengths which are diagnostic of physical phenomena The 7.85-micron image in the upper left shows stratospheric temperatures which are elevated in the region of the A framgnet impact (to the left of bottom). The distribution of ammonia at different atmospheric levels is shown by the 10.5- and 10.7 micron images in the right-hand panel. The strong emission indicates that ammonia has been transported from the tropopshere at or below the 0.6 bar level to the warm stratopshere by the explosion. To the lower left is an image in ethane-sensitive 12.2-microns showing enhanced emission at this same impact location, indicating elevated temperatures or enhanced abundances of ethane.
