Astrometric results of the mutual events between the Galilean satellites during 2014–15

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.
