5 Conclusions

During the periods of mutual eclipses and occultations of the Jovian satellites, which occur every six years, several mutual events involve the small inner satellites with a Galilean satellite. Due to the difficulty of observing such an event, no data have been obtained until now during previous campaigns. However, photometric observations of such events could give access to incomparably accurate astrometric measurements, useful for the dynamical modeling of these faint satellites. In this paper, we give a list concerning the most observable events of J5 Amalthea eclipsed by Io over the period November 2002 to June 2003. We hope that astronomers interested in these problems will join the international campaign that we have organized in order to succeed in these observations.
