Abstract: The 811 observations of the 2009 WZ104 asteroid were obtained with telescopes of Pulkovo observatory. Obtained observational data allow to improve the accuracy of estimated asteroid orbit, to determine its absolute magnitude in B, V, R, I bands, color-indices, rotation period, taxonomic class (R or Q) and to estimate its physical parameters.

Keywords: astrometric and photometric observations, near Earth asteroid.
