Contrast of Filament Bright Rims

Hα filtergrams were measured in order to specify the bright rims contrast at different points along the line profile. The mean contrast value in the line center is about 25 percent. The bright rims interpretation as the bases of magnetic structures supporting the filaments is suggested.
