This image was obtained with the TIMMI instrument at the ESO 3.6-metre telescope on July 18, 1994, 20:11 UT. It shows the rising plume above the impact site of fragment H of comet Shoemaker-Levy 9. The image was made in the 9.1 - 10.4 micron band in the far-infrared region.
The surface brightness of this plume was about 50 times that of the Jupiter disk. The temperature was measured as more than 300 K.
The observers were Tim Livengood (NASA), Ulli Kaeufl (ESO), Benoit Mosser and Marc Sauvage (Observatoire de Paris-Meudon, France).
