“…Arlot (2008) compiled predictions of all 2009 events using the G5 ephemerides based on Lieske's theory (Lieske 1977) and the newer L1 ephemerides from Lainey et al (2004a,b) for the motion of the Galilean satellites; 370 observable mutual events were computed. Before 2009, several observational campaigns were completed during previous occurrences (Arlot 1992(Arlot , 1997(Arlot , 2006. Table 1 presents the results derived for each campaign up to the present campaign.…”

Context. In 2009, the Sun and the Earth passed through the equatorial plane of Jupiter and therefore the orbital planes of its main satellites. It was the equinox on Jupiter. This occurrence made mutual occultations and eclipses between the satellites possible. Experience has shown that the observations of such events provide accurate astrometric data able to bring new information on the dynamics of the Galilean satellites. Observations are made under the form of photometric measurements, but need to be made through the organization of a worldwide observation campaign maximizing the number and the quality of the data obtained. Aims. This work focuses on processing the complete database of photometric observations of the mutual occultations and eclipses of the Galilean satellites of Jupiter made during the international campaign in 2009. The final goal is to derive new accurate astrometric data. Methods. We used an accurate photometric model of mutual events adequate with the accuracy of the observation. Our original method was applied to derive astrometric data from photometric observations of mutual occultations and eclipses of the Galilean satellites of Jupiter. Results. We processed the 457 lightcurves obtained during the international campaign of photometric observations of the Galilean satellites of Jupiter in 2009. Compared with the theory, for successful observations, the r.m.s. of O-C residuals are equal to 45.8 mas and 81.1 mas in right ascension and declination, respectively; the mean O-C residuals are equal to -2 mas and -9 mas in right ascension and declination, respectively, for mutual occultations; and -6 mas and +1 mas in right ascension and declination, respectively, for mutual eclipses.

“…Such campaigns, as organized in the past, allowed publication of a very complete catalogue of data such as in Arlot et al (1997) for the 1991 occurrence and in Arlot et al (2005) and Emelianov et al (2000) for the 1997 occurrence. The reader is encouraged to join our campaign of observations, to contact the authors at arlot@imcce.fr, and to get information on the campaign of observations from the web address www.imcce.fr/pheura07.…”

“…For CCD observations, images were measured by Gaussian photometry of the ASTROL software . Two dimensional measurements allow us to calibrate the signal of the involved satellite to the signal of a nearby satellite, to substract the sky background in real time and so to obtain data under very difficult conditions (see for example Arlot et al 1997).…”

Abstract. In 1994-1996 the Sun and the Earth passed through the equatorial plane of Saturn and therefore through the orbital planes of its main satellites. During this period, phenomena involving seven of these satellites were observed. Light curves of eclipses by Saturn and of mutual eclipses and occultations were recorded by the observers of the international campaign PHESAT95 organized by the Institut de mécanique céleste, Paris, France. Herein, we report 66 observations of 43 mutual events from 16 sites. For each observation, information is given about the telescope, the receptor, the site and the observational conditions. This paper gathers together all these data and gives a first estimate of the precision providing accurate astrometric data useful for the development of dynamical models.
