[en] An active region emission loop has been reconstructed, its true form and size have been determined. The loop proved to be almost vertical to the solar surface and only slightly inclined in its own plane. The loop matter has been found to rize from the solar surface along one leg with velocities 105-35 km/s and to descend in other leg with velocities 14-65 km/s. The loop hasbeen shown to have a close correspondence to the magnetic dipole field line
