Description
For three Ap stars (53 Cam, 41 Tau and β CrB) relative fluxes in the central part of K Ca2 line were measured in the range Δlambda = 2.8 A. For 41 Tau fluxes in Hβ line were also measured. Flux variations both with axial rotation period and at time intervals ΔT approximately 1sub(h) were found. In the case of 53 Cam during one night the flux oscillations were of sinusoidal type with a period P1 28sub(m).7 +- 1sub(m).4 and amplitude of 5%
