Periodical brightness gradient differences between extreme (mu less than 0.2) west and east limb darkening profiles of the Sun are shown from diametrical high speed scans obtained by the use of the heliometer. Time series of data display, in the five-minute range, several frequencies with amplitudes of difference corresponding to 2 to 4 percent of the mean brightness gradient value in the 678 nm wavelength range. One of these periods (270 s) was previously exhibited by Hill et al. (1982) and later by Koutchmy et al. (1983). These results might be related to asymmetries of solar limb darkening observed by Neckel and Labs (1987). A solar origin is discussed.
