“…The characteristics of such phenomena and the results of observations are described in many publications (see e.g. Arlot et al 1982Arlot et al , 1992Arlot et al , 1997Emelianov et al 2000;Arlot et al 2006). Astrometric reduction of these observations was performed by a number of authors (Aksnes & Franklin 1976;Aksnes et al 1984;Vasundhara 1991;Emelianov et al 2000;Vasundhara 2002;Vasundhara et al 2003).…”

The photometry of mutual occultations and eclipses of natural planetary satellites can be used to infer very accurate astrometric data. This can be achieved by processing the light curves of the satellites observed during international campaigns of photometric observations of these mutual events. This work focuses on processing the complete data base of photometric observations of the mutual occultations and eclipses of the Galilean satellites made during the international campaign in 2002–2003. The final goal is to derive new accurate astrometric data. We propose the most accurate photometric model of mutual events based on all the data available to date about the satellites, and develop the corresponding method for extracting astrometric data. This method is applied to derive astrometric data from photometric observations of mutual occultations and eclipses of the Galilean satellites. We process the 371 light curves obtained during the international campaign of photometric observations of the Galilean satellites in 2002–2003. As compared with the theory, the rms ‘O‐C’ residuals with respect to theory is equal to 0.055 and 0.064 arcsec in right ascension and declination, respectively, for the 274 best observations. Topocentric or heliocentric angular differences for satellite pairs are obtained for 119 time instants during the time period from 2002 October 10 to 2003 July 17.

“…On the basis of the results of the international campaign in 1973 of the mutual events of the Galilean satellites, Aksnes (1976) showed that differences in the observed and predicted mid times and depths of the events can be used to revise the orbital constants of the theory. Subsequent International campaigns and analysis of the observations during the 1979, 1985, 1991, 1997, 2003 and 2009 apparitions have provided an extensive data set of inter satellite astrometric positions (Aksnes et al 1984;GSO 1991;Vasundhara 1991;Arlot et al 1992;Mallama 1992;Vasundhara 1994;Arlot et al 1997;Kaas et al 1999;Vasundhara 2002;Vasundhara et al 2003;Arlot et al 2006Arlot et al , 2009Emelyanov 2009;Dias-Oliveira 2013;Arlot et al 2014).

Results of analysis of 23 events of the 2014-2015 mutual event series from the Vainu Bappu Observatory are presented. Our intensity distribution model for the eclipsed/occulted satellite is based on the criterion that it simulates a rotational light curve that matches the ground based light curve. Dichotomy in the scattering characteristics of the leading and trailing sides explain the basic shape of the rotational light curves of Europa, Ganymede and Callisto. In case of Io the albedo map from USGS along with global values of scattering parameters work well. Mean values of residuals in (O − C) along and perpendicular to the track are found to be -3.3 and -3.4 mas respectively compared to "L2" theory for the seven 2E1/2O1 events. The corresponding R.M.S values are 8.7 and 7.8 mas respectively. For the five 1E3/1O3 events, the along and perpendicular to the track mean residuals are 5.6 and 3.2 mas respectively. The corresponding R.M.S. residuals are 6.8 and 10.5 mas respectively. We compare the results using the chosen model (Model 1) with a uniform but limb darkened disk (Model 2). The residuals with Model 2 of the 2E1/2O1 and 1E3/1O3 events indicate a bias along the satellite track. The extent and direction of bias is consistent with the shift of the light center from the geometric center. Results using Model 1, which intrinsically takes into account the intensity distribution show no such bias.

Since 2003 the Planetary Virtual Observatory and Laboratory (PVOL) has been storing and serving publicly through its web site a large database of amateur observations of the Giant Planets (Hueso et al., 2010a). These images are used for scientific research of the atmospheric dynamics and cloud structure on these planets and constitute a powerful resource to address time variable phenomena in their atmospheres. Advances over the last decade in observation techniques, and a wider recognition by professional astronomers of the quality of amateur observations, have resulted in the need to upgrade this database. We here present major advances in the PVOL database, which has evolved into a full virtual planetary observatory encompassing also observations of
