Two-dimensional power spectrum of TW Vir calculated from a moving window 1.6 day is overplotted with its K2 light curve in magnitudes. A horizontal dash line at Kp₂ = 15.3 mag is arbitrarily used to distinguish the two luminosity states: outburst and quiescence. The light curve between the two vertical dash lines lasting ~3.7 days may denote the rebuilding process of the orbital modulation that was interrupted by the superoutburst.
