Fragment A Impact Fragment A Impact

This images comes from the 3.5-meter telescope at Calor Alto Spain. A methane blocking filter was used at a wavelength of around 2.3 microns in order to maximimize the contrast of the structure in the Jovian atmosphere. IO is very bright at this wavelength and is indicated by the Green arrow. The initial impact of Fragment A produced a spot/plume that rivaled the brightness of Io for a few seconds and then later faded. The timesequence stars from the upper left and runs counterclockwise to the upper right.

Hubble Space Telescope Image

This is a violet picture (wavelength around 4000 angstroms) which shows a dark spot marking where the Fragment A entered the Jovian Atmosphere. This is a good example of the scale of the damage, about 1/2 the size of the Great Red spot.

La Silla Image Sequence This sequence will show the development of the plume from Fragment A as well. These again are pictures in the infrared, in this case around 10 microns. The images are short exposures taken over a time internal of 3 minutes. What is surprising and unexpected in this sequence is the rapid fading of the hot spot. This is likely a consequence of very rapid cooling. These images come courtesy of the European Southern Observatory
