Observed changes in the radio structure over time.

Demonstrated the effectiveness of MFS in reconstructing detailed radio maps.

Abstract

We analyze results of data processing of observations of well-known object titled SS433 with the VLBA during more than 10 years. Data have been processed with the software project titled 'Astro Space Locator' (ASL for Windows). The Multi Frequency Synthesis (MFS) method has been used for reconstruction of radio maps at 18 and 6 centimeter wavelength ranges (L and C ranges). High quality images of SS433 for several epochs are presented. Evolution of its radio structure is demonstrated. Astrophysical parameters of object and their changes in time are discussed. Any polarization phenomena are not taken into account. We present results of processing of data of RR polarization for all the observational sessions
