Top: UBV light curves of Z And from 1981 covering its quiescent and active phases. References for the data used are in Skopal et al. (2000). Bottom: current active phase that started in 2000 September showing multiple outbursts. Vertical bars indicate times of our spectra (Table 1). The presence of bipolar jets is denoted by vertical gray belts. No jets were indicated during the major 2000–03 outburst (Skopal et al. 2006) and during 2011–12 and 2014 brightenings (Figure 3). Data are described in Section 2.2.
