Shoemaker-Levy 9: the W-impact (2)

These four images of Jupiter and the luminous night-side impact of fragment W of Comet Shoemaker-Levy 9 are different versions of an average of 8 images taken by the Galileo spacecraft of July 22, 1994.
The frames that were averaged span about 30" near 8:06 UT.

These four "averaged" images show the scene without and with (top and bottom) spatial filtering and contrast enhancement, and without and with (left and right) a latitude/longitude grid. Grid spacing is 30 degrees, with 230° Longitude centered. The terminator is at about 265°. The impact location is about 43° South, as predicted, and at 280° Longitude. The dark spots to the right of the flash are from previous impacts.
