  "abstract": "We report the results of observations of a WZ Sge-type dwarf nova ASASSN-14cv, acquired in 2014 and covering the end of a superoutburst and a rebrightening stage. We detected 8 rebrightenings of this star. Based on the light curve profiles of the rebrightenings, we conclude on the existence of both the \"inside-out\" and \"outside-in\" outbursts. During the entire course of the rebrightening stage, a brightness variability with the mean period of P = 0.(d)06042(8) was detected, which was identified as a superhump period during the stage B of the superoutburst. The character of the registered superhump evolution can be either described by a parabolic approximation with the negative P (dot) = -1.1 x 10(-5), or by an approximation with 2 linear areas with the corresponding periods of 0.(d)06074(3) and 0.(d)06046(9).",
