Velocity evolution from the P-Cygni absorption minima of the most important spectral lines for our PTF and CCCP SNe (colored symbols) as compared to SN 1987A and other long-rising SNe II (black symbols, from the spectra presented by Phillips et al. 1988; Pastorello et al. 2005, 2012; Taddia et al. 2012). Typical uncertainties are of 500–1000 km s-1.
