In August/September 1999, we observed several active regions during their disk passage on the Sun. The data set consists of speckle reconstructed continuum images at 520~nm, near infrared continuum obtained at 1565~nm with frame selection, and line-of-sight magnetograms. All these data were taken simultaneously. We studied the horizontal motions of sunspots, pores, and faculae by tracking features in the continuum filtergrams with sizes close to the diffraction limit of the 65~cm vacuum refractor at the Big Bear Solar Observatory. We undertake this study to gain a better understanding of the development of active regions and the emergence of magnetic flux. We focus our attention on the dynamics of small-scale magnetic features such as rudimentary penumbrae, penumbral grains, magnetic knots, and filigree. Finally, the results of this analysis will illustrate the prospects for near real-time image reconstruction and application oriented parallel computing.
