Phobos and Deimos CCD observations

Aims. This paper give positions of Martian satellites system from CCD observations obtained at the Cassegrain focus of a 1.6 m reflector for the years 1995 and 2003. Methods. These positions were reduced using the scale and orientation parameters, determined from star field positions of Uranus and Pluto systems’ observations that were made in the same night as Mars observations. Results. They are compared with the theoretically calculated positions from JPL Development planetary Ephemeris – DE405. The standard deviations of the residuals, observed minus calculated positions, right ascension and declination of Phobos and Deimos, respectively are σ = 0. �� 079 and σ = 0. 072.
