Description:
The results of coordinated Crimea-Dodaira simultaneous multi-bands
photometric and polarimetric observations of the classical Herbig
Ae/Be star RR Tau which cover fully the observed interval of its
brightness changes are presented. Within the observed interval of its
light variations the linear polarization of RR Tau anti-correlates
with its brightness changes.
