Abstract
Data from the first long series of photometric observations of the two little-studied polars SDSS J032855+052254 and SDSS J215427+155713 (SDSS J0328 and SDSS J2154 in the following) at the Crimean Astrophysical Observatory and at the Terskol Observatory in integrated light and in the BVRc bands are analyzed. The orbital periods are refined and the orbital ephemerides are determined for the first time using these data. Two pole accretion is observed in SDSS J0328. High accuracy observations with a resolution of 15 s reveal oscillations in the brightness with a characteristic time of about 4 min and an amplitude as high as 0m.5. Based on the color indices for SDSS J2154, it is found that over the orbital cycle, there are several sources which contribute to the brightness variation with emission maxima in different spectral ranges.
