                           SATELLITE LOCATOR 
                              for Jupiter

  GALSAT is a PC MSDOS program that will predict and display the positions
of the Jupiter's four largest moons, the Galilean Satellites: Io, Europa, 
Ganymede, and Callisto.  The program is designed for VGA or SVGA monitors.
A CGA version is also available by request.  GALSAT is the improved
version of JUPIT, a program posted to sci.astro newsgroup last year.
                   
  One can determine when one of the moons cast a shadow on Jupiter
or when a moon is eclipsed by Jupiter with reasonable accuracy using the
program.  The program displays the positions from two perspectives:
from above Jupiter and as they appear though Earth-based telescopes.
Also a one week prediction chart is shown.  On-line help is available
as well as references.  Thanks to all who made suggestions or comments.
I've tried to implement your ideas in this latest version.

  This program may be useful in predicting the locations of of Jupiter's
moons during the impact of comet Shoemaker-Levy next year.  The comet
impact is said to take place on the far side of Jupiter so that the light
from the fireballs produced may only be seen by reflections for Jupiter's
moons. Please send suggestions or comments to astro@tamu.edu.
