This photo was obtained with the IRAC 2B near-infrared instrument at the MPI/ESO 2.2-metre telescope on July 18, 1994, 03:10 UT (05:10 CEST; 23:10 Chilean time).
It shows the plumes associated with the impacts of fragments A (below, left) and E (below, right) of comet Shoemaker-Levy 9, as seen at a wavelength of 2.1 micron. On this photo, the plume of the F-impact (to the right of the E-plume, under the Great Red Spot in the middle) is too faint to be well seen. The A-plume has just completed its fourth rotation since it was created by the impact of the A-fragment in the evening of July 16. The astronomers are surprised by the apparently long life of these new features.
Please note that the data are the property of the observing team, led by Klaus Jockers (Max-Planck-Institute fuer Aeronomie, Katlenburg-Lindau, Germany).
