We have investigated variations in the strength and profile of the Hα emission line in the spectrum of Algol using 145 16 A° mm−1 spectrograms obtained during the period September, 1976 to December, 1977. The Hα emission line profile has been extracted by subtracting the absorption contributions of the three stars in the system. The resulting data set has been analyzed to look for variations related to orbital phase as well as shorter and longer term variations.
