N2 - We present the results of synchronous photometric and polarimetric UBV RI observations of the irregular variable star RZ Psc, acquired at the Crimean Astrophysical Observatory in 1989-2002. The star's photometric behavior is characterized by short, sporadic Algol-like dimmings. We observed only one deep minimum, with a V amplitude of about 1.5m, during the entire observation time. During this minimum, the star's linear polarization reached 3.5%. Comparisons with polarization observations of RZ Psc during another deep minimum in 1989 show that the two minima can be described by the same polarization-brightness relation, testifying to an eclipsing nature for the minima. This provides evidence that the optical characteristics of the flattened circumstellar dust envelope that gives rise to the star's intrinsic polarization have remained virtually unchanged over the last 13 years. We argue that the origin of this stability is the presence of a large dust-free cavity in the central region of the circumstellar dust disk of RZ Psc.
