TIMMI OBSERVES DRAMATIC IMPACT ON JUPITER (esoimpact-a.gif)
This series of seven images was obtained with the TIMMI far-infrared
instrument at the ESO 3.6-metre telescopes on July 16, 1994, between
20:23 UT and 21:26 UT (22:23 to 23:26 CEST). It shows the plume rising
above the site of the impact of fragment A of comet Shoemaker-Levy
9. The predicted impact time was 20:00 UT, or 23 minutes before the
first image was obtained.
These images document an absolutely unexpected, very rapid cool-down
of the impact region. The filter was N2 at 9.4 to 11 micron. The scale is
0.6 arcsec per pixel.
Please note that the data are the property of the two observing teams.
The observers were: Benoit Mosser (DESPA/Meudon, France), Tim
Livengood (National Research Council/ NASA Goddard Space Flight Center,
Greenbelt, Maryland, USA) and Ulli Kaeufl (ESO).
This series together form ESO PR Photo SL9J/94-10 which accompanies
the ESO SL-9/Jupiter Information Package. It may be reproduced, if
credit is given to the European Southern Observatory.
