Scientific paper

Mass motions in active region filaments of regions NOAA 4171 and McMath 16208 are analyzed. Matter in the long-lived filaments, which lie along the magnetic neutral lines, flows generally horizontally and along the axes of the filaments. Since the matter in the filaments is considered to flow along the magnetic field, the magnetic fields in the filaments must be highly sheared. The same patterns of mass flow are found in the same filaments on successive days. Some filaments show long-lived symmetrical downflows to both of their ends in which the velocity is about 30 km/s. Such flows are seen both in NOAA 4171 and McMath 16208.
