摘要：

We analyze a time series of high-resolution observations near the limb, in the continuum, in the Mg b(1) line (-0.4 Angstrom off line center), and in the wings of H alpha (+0.75 Angstrom). The observations were obtained with a CCD camera at the Vacuum Tower telescope of the Sacramento Peak Observatory. We study the association of facular points, as they appear at different heights of the solar atmosphere (continuum, b(1) - 0.4 Angstrom, H alpha + 0.75 Angstrom) with the feet of fine dark mottles.
