Abstract

Multiple photoelectric photometry of the Delta Scuti variable 4 Canum Venaticorum was obtained during 1983 and 1984, and five pulsation frequencies with visual amplitudes between 0.014 and 0.005 mag were found. The observed frequencies indicate nonradial pulsation with p1, p2, and p3 modes. The amplitudes of these frequencies were nearly constant in 1983 and 1984, in contrast to the pattern over 18 yrs.
