Light curves of our targets and those of different young eruptive stars. Triangles: photographic light curve of V1057 Cyg from Gieseking (1973); stars: IC light curve of V1647 Ori from Acosta-Pulido et al. (2007); squares: visual light curve of EX Lup during its extreme outburst in 2008 (Ábrahám et al. 2009). For HBC 722 and VSX J205126.1+440523 we plotted the R-band light curves. The data for V1057 Cyg, V1647 Ori, and EX Lup were shifted along the y axis for better visibility and also along the x axis so that the peak brightness is approximately at the same position for all stars.
