摘要：

The configuration of the magnetic field in an active region is analysed using a set of HP chromospheric magnetograms and narrow pass-band filtergrams taken at various positions on the line. We found that the chromospheric magnetic field is parallel to the chromospheric features and inhomogeneous. The photospheric magnetic field disappears abruptly in the edge of the penumbra; the chromospheric held extends beyond the penumbral boundary with an inclination of about 10 degrees-20 degrees to the solar surface. Chromospheric superpenumbral filaments show a good correlation with the chromospheric magnetic field and their configurations are related to the photospheric magnetic structures nearby the sunspot. Part of the magnetic flux of the sunspot returns to the neighbouring enhanced networks, which is almost vertical to the solar surface.
