Abstract

Abstract: Photometric observation of mutual events between planetary satellites can be used to obtain their high accurate astrometric data. The mutual events between the Galilean satellites occur every six years. During 2014–15, 12 mutual events between the Galilean satellites were observed using 1.0 m telescope in Kunming and the fourth of Burst Optical Observer and Transient Exploring System (hereafter Bootes-4) 0.6 m telescope at Lijiang station of Yunnan Observatories, Chinese Academy of Sciences, and the astrometric results of such mutual events will be given in this paper. Highlights: Twelve light curves of the mutual events between Galilean satellites are provided. Astrometric results of Galilean satellites are obtained by fitting the light curves. Our results will be very helpful to improve the dynamical theory of Galilean satellites.
