Occultazioni ed eclissi tra i satelliti medicei: i risultati della campagna PHEMU09 in Italia

Results of photometry of mutual phenomena between Galilean satellites are presented. The observations were performed in Italy during the international campaign PHEMU09.Relevant deviations (O-C) with respect to the expected central instants are present for many events. Taking into account the relative satellites’ longitudinal velocity, longitudinal discrepancies in km (and arcsec) are also computed. The discrepancies with respect to the expected flux drops during the occultations are apparently uncorrelated with the O-C on timing (and longitudinal deviations in km); moreover, for eclipses they seem greater than for occultations
