Photoelectric observations of the integrated fluxes of Mars, Jupiter, and stars in the case of a signal integration time of 20 ms for different telescope apertures are reported. The quadratic mean square flux fluctuation is found as a function of the angular size of a source and of the aperture. The scintillation parameters for Mars obtained with an 8-cm aperture are used to simulate the effect of scintillations on the darkening function near the solar limb, which is determined from eclipse observations. The scintillations are found to substantially affect the results. Averaging of several curves distorted by scintillations yields an almost monotonic decrease in brightness at the extreme limb.
