The 11-hour series of high-resolution white light frames of a large pore was analyzed to study the evolution of a filamentary region attached to the pore, horizontal motions around the pore, and small-scale morphological changes. It was found that the filamentary region, although having some typical penumbral features, was different from a normal penumbra.
