Description

Intensities of Hα-emission line of five rapid irregular variables (SV Cep, V 530 Cyg, XY Per, VV Ser and WW Vul) have been investigated. 18 spectra of the stars were obtained at the 2.6 m telescope of the Crimean Astrophysical Observatory using the slit spectrograph with the image intensifier. Hα-luminosity of four stars ranged within (0.93-16.1)x1032 erg.s-1. The variability of the emission line intensities is underlined. Spectrum of the V530 Cyg has not the bright Hα-line
