Abstract : The question of whether or not the variations in intensity of spectrum variables are strictly periodic and stable over long periods of time is discussed. 56 Arietis affords one test of this question because of its exceptionally short period of variation and the availability of previous data. An attempt was made to investigate the intensity variation of the He I liner and the Si II lines. The strengths of H epsilon and H gamma were investigated in order to ascertain if short period fluctuations in equivalent width of an angstrom or more occur in 56 Arietis.
