Scientific paper

Preliminary analysis of observational accuracy and identification of celestial objects can be performed directly on site using the appropriate software. Such software has been developed at the Institute of Theoretical Astronomy and the Pulkovo Observatory. In particular, it is reasonable to derive the object's normal place for a certain date and the first-order apparent motion parameters, i.e., the first derivatives of its spherical coordinates or the absolute value and direction of the object's topocentric angular velocity. These parameters are shown to be of great importance for the derivation of ephemerides and for the identification of objects observed using only the station's own observations performed within an interval up to a few weeks. Two software packages - CERES and LAPLACE - can be useful when performing a quick analysis of dense CCD observations of the minor bodies in the solar system and for the preliminary orbit determination and identification of the object.
