Abstract
We present photometric observations of two polar candidates, IPHAS J052832.69+283837.6 and 1RXS J073346.0+261933. Both objects reveal brightness variations related to the orbital period with an amplitude of about 1m, and about 0ṃ5 on the long-termscale. The object IPHASJ052832.69+283837.6 also exhibits variations of color indices and light curve shape. Long-term observations allowed us to determine the orbital period of the first system and refine the orbital period of the second system, which proved to be \({P_{ord}} = 0_.^d055593(4)\) and \({P_{ord}} = 0_.^d139095(2)\) respectively. The photometric data analysis proves that these systems are polars.
