This photo was obtained with the TIMMI far-infrared instrument at the ESO 3.6-metre telescope on July 18, 1994, 03:03 UT (05:03 CEST; 23:03 Chilean time).
It shows the planet's emission at 5 micron wavelength. In addition to the complex bands which delineate the various streaming motions in the atmosphere, plumes are seen that are associated with the impacts of the cometary fragments E (at latitude -45 degrees, to the left of the centre of the disk), and fragment F, which entered the atmosphere about two hours earlier (same latitude, to the right of E, and just below the Great Red Spot that is seen a dark oval feature).
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. It may be seen as a weak feature at the left (eastern) limb and same latitude.
Please note that the data are the property of the observing teams, led by Tim Livengood (NASA Goddard Space Flight Center) and Benoit Mosser (Observatoire de Medon-Paris)
