Tom Polakis has recommended the program, WinJupos, which evidently predicts Jovian events accurately. http://www.grischa-hahn.homepage.t-online.de/astro/winjupos/index.htm WinJuposGuide in English http://alpo-j.asahikawa-med.ac.jp/Latest/WinJUPOS/winjuposcuide_english.html I am not familiar with the WinJupos program, but Tom has evidently had good success using it. You might also look at GUIDE software (by Bill Gray at Project Pluto), which is popular amongst the IOTA occultation and MPML (minor planets) communities: http://www.projectpluto.com/ There is also JupSat pro (not free) software: http://www.nightskyobserver.com/JupSatPro/ For just an informal graph of relative Jovian satellite positions, there are freebie Windoze (DOS) programs available from Dr. Dan Bruton of Stephen F. Austin State U. (SFASU): http://www.midnightkite.com/dansoftware.html Look for Galsat and Satsat: http://www.physics.sfasu.edu/astro/software/galsat53.zip Also there is JupSat95: http://indigo.ie/~gnugent/JupSat95/ Have fun, Gene Lucas (17250) Paul Lind wrote: > AJ, > I didn't see any images of that conjunction.
