Notes. Symbols: n, w general narrowing/widening of emission lines’ width with time, n – w emission line narrowing before widening, w – n emission line widening before narrowing. Notes: after maximum (a) very rapid widening of the emission line (b) no absorption seen; (c) Hα width, probably no diffuse-enhanced absorption system seen; (d) width stable when seen; (e) width of each emission component of profile increasing.
