Abstract:
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 ).

Note (1): Nature of the event:
1 OCC 2 means that satellite 1 occults satellite 2
3 ECL 4 means that satellite 3 eclipses satellite 4
Note (2): Type of eclipse:
P: partial
A: annular
T: total
blank: eclipse by the penumbra
Note (3): Flux drop:
if 0, grazing event with a very small signal to be detected;
if 1, total event with a large signal easy to detect.
Note (4): No duration is indicated for grazing events.
