  We present photometric and polarimetric observations of a new magnetic
cataclysmic variable, presumably a polar, USNO-A2.0 0825-18396733. The
photometric observations were carried out with the SAO RAS Zeiss-1000
telescope, and the polarimetry was performed with the 6-m BTA telescope. The
redefined orbital period P = 0:d08481(2); the brightness of the system varied
from 17:5 to 20:0 in the Rc filter. Polarimetric observations of the object in
the V filter revealed strong variable circular polarization: -2% to over -31%.
This indicates that the variable USNO-A2.0 0825-18396733 is a polar.
