		| Abstract: | 
		The BL Lac object 3C 66A was a target of hotopolarimetric monitoring in UBVRI bands from 1993 till 2002. We present the results of our observations in R band. The intrinsic polarization of the object consists of large (13.6%) constant and variable components along the preferred direction. The correlated variations of the brightness and polarization parameters are considered as support for the precession of the jet. |
