Abstract

We present the results of the first year of searching for polar candidates within the 3BS (3-Band Survey) program using medium-band filters. Observational data for 84 selected objects from the catalog of cataclysmic variables of the CRTS DR1 sky survey were obtained while implementing the program. A dwarf nova during its outburst and a polar were detected. The available archival data are analyzed. The dwarf nova is of the U Gem or Z Cam type and contains a massive secondary component with \(M_{2}=0.94\pm 0.04M_{\odot}\). For the polar found we have estimated the orbital period \(P_{O}=0\overset{d}{.}054437\) and calculated the magnetic field strength of the white dwarf \(B\approx 32\) MG.
