Eclipses and Occultations of Galilean Satellites Observed at Yunnan Observatory in 2003

摘要

We describe and analyze observations of mutual events of Galilean satellites made at the Yunnan Observatory in February 2003 from CCD imaging for the first time in China. Astrometric positions were deduced from these photometric observations by modelling the relative motion and the photometry of the involved satellites during each event.
