Abstract:
In 2003, the Sun and the Earth passed through both the equatorial
plane of Jupiter and therefore the orbital planes of its main
satellites. During this period, mutual eclipses and occultations were
observed and we present the data collected. Light curves of mutual
eclipses and occultations were recorded by the observers of the
international campaign PHEMU03 organized by the Institut de Mecanique
Celeste, Paris, France
We completed 377 observations of 118 mutual events from 42 sites and
the corresponding data are presented in this paper. For each
observation, information about the telescope, receptor, site, and
observational conditions are provided. This paper gathers all data and
indicates a first estimate of its precision. This catalogue of these
rare events should constitute an improved basis for accurate
astrometric data useful in the development of dynamical models.
