Abstract

This is the fourth in a series of papers which, as was explained in Papers I, II, and III (Lovell and Hall 1970; Lovell and Hall 1971; Landis, Lovell, and Hall 1973), should be helpful in understanding the changes in the light curve of β Lyrae. Betwen March and October of 1972, 82 differential UBV observations were obtained by Lovell and 107 by Landis. NOTE: an erratum is published in JAAVSO (1974) Vol. 3, p. 35
