Abstract
Equivalent width measurement is one of the methods used to study the spectral line profile. It has been associated with the strength of spectral lines and the amount of absorbance of particular element. In this study, we analyzed the spectra of 22 Vulpeculae obtained from Ritter Observatory archive data. The equivalent width (EW) of Hα from this star showed some changes over the 8 years period.
