Mutual occultations and eclipses of the Galilean satellites of Jupiter will occur in 2002-2003. This paper provides predictions of these events as well as information useful for their observations. Such events are uncommon, since they occur only every 6 years when the Earth and the Sun pass through the common orbital plane of the Galilean satellites. Therefore, we encourage professional and amateur astronomers to join the networks of observers in order to get as many observations as possible. Data on the predictions of the events are available on the web server of the Institut de Mecanique Celeste et de Calcul de Ephemerides (IMCCE) ( http://www.bdl.fr ).
