Limb Darkening VariationsVariations of the solar limb darkening as measured in the line wing of the Fe I line at wavelength 5,250 are observed. The measurements are made over the visible solar disk excluding those points where the magnetic field strength exceeded five Gauss. This exclusion of magnetic points should reduce the effects of faculae upon the derived limb darkening curve. The observations cover 160 days and show evidence of variations of 0.002 I(0) over timescales of thirty days.
