We analyze the cycles in V795 Her, the optical counterpart of 2RXP J171256.0+333121, using the V band CCD observations. We show that while the smoothed profile of the folded intensity curve of the known cycle of ~2.8028 hours is single-peaked, the profile of its residuals is double-peaked. We discuss our observations in terms of superhumps.
