Abstract

We present the results of short observational program of asteroid 6478 Gault with using of V and R Johnson filters realized at the Kyiv Comet Station during January -April 2019. Color indices and distribution of brightness in the comet-like tail were calculated. We made a comparative analysis of circumstances of the asteroid 6478 Gault activity with others morphologically similar active Main Belt asteroids.
