Spectral observations of the flare star EV Lac made on the 2.6-m telescope at the Byurakan Observatory in 2000-2002 are reported. A powerful flare was detected and it was possible to follow the variation in the equivalent widths of the Hα and Hβ lines, both during the flare and during the quiescent phase of the star. It is shown that the profiles and equivalent widths of the lines underwent substantial changes. The equivalent widths of these emission lines reached a maximum roughly 40 min after the flare maximum.

Spectra of five condensations in theHerbig Haro object HH 448 are presented for the first time. The emission line intensities indicate a low degree of ionization, 3 5%, with an electron density of 10 3 10 4 cm 3 . The relative intensities of the emission lines of the individual condensations show that their physical properties differ. We classify the two stars closest to HH 448 as main sequence dwarfs which are, most likely, not coupled to HH 448. The absorption in the region of HH 448 is at least 4 m .3.
