The polarization degree $p$ of RW Aur A at this period has reached 30 per cent in the $I$ band. As in the case of UX Ori type stars (UXORs), the so-called 'bluing effect' in the colour-magnitude $V$ versus $V-R_{\\rm c},$ $V-I_{\\rm c}$ diagrams of the star and a strong anticorrelation between $p$ and brightness were observed.
