The following sets of postscript charts can be used at the eyepiece to identify impact regions on Jupiter from fragments of the Shoemaker-Levy 9 comet. The 12 charts for each evening cover the period from 8 p.m. to 11:45 p.m. EDT (0H to 3:45H UT on the day following).
The charts are also useful for identifying spots on the images if the image time is known.
The charts were produced by applying minor modifications to the source code of a program written in IDL by Jason Goodman (GOODMANJ@carleton.edu) which he was kind enough to provide in a limited distribution for this effort.
Here is part of Jason's README file:
******These procedures written by Jason Goodman, Summer, 1994***********
This program generates a series of postscript maps of the visible
disk of jupiter, and currently visible impact points on the disk. Only
impacts which are verified by observers to have created splotches on the
planet are shown. These are marked with the letter of the fragment which
generated them: the size and line thickness of the letter indicate
qualitatively the size and intensity of the impact remnant. Longitudes
are based on data from the Hubble Imaging Team.

The charts are in PostScript. They may be viewed directly if you have a viewer such as Ghostview, or they may be downloaded to disk and then sent to a PostScript printer. To download to disk select Load to Local Disk under the Options menu of Mosaic. Do that now. Then click on the desired chart to download it.
