An accuracy estimation of CCD asteroid observations contained in the Minor Planet Center Database and carried out in the years 1999 - 2006 is realized. About 20 millions individual positions of the Numbered and Unnumbered Minor Planets were tested by means of calculations of (O-C) residuals to derive "mean error of a single observation" for more than 400
