Photometric observations of V1674 Her (ATel #14704) were carried out during the outburst decline From 40 to 55 days after the maximum of the outburst (JD 2459417-434). We found the optical BVRcIc modulation with a period of 0.15290(3) days. The profile of the light curve has amplitude close to 0.12 mag and shows two unequal minima separated by half a period. We assume that this period may be caused by orbital motion. The light curve folded with ephemeris JD hel min = 2459426.327+0.1529*E is presented in Figure.
