Hα broad wings (left panels) and short-term variability in the optical continuum (right panels) at different stages of Z And activity. During the 2006 and 2009–10 major outbursts, when the satellite S− and S+ components emerged, a slow higher-amplitude photometric variation developed (Section 3.1). Data from 2006 and 2007 were published by Skopal et al. (2009). Fluxes are in 10−12﹩\,\mathrm{erg}\,{\mathrm{cm}}^{-2}\,{{\rm{s}}}^{-1}\,{\mathring{\rm A} }^{-1}﹩.
