A series of spatial intensity profiles across the sunspot penumbra is obtained at different wavelengths within the CaII K line (see Figure 1). A number of photometric properties of the penumbra are outlined, which may be useful for constructing a relevant inhomogeneous model.

From investigating spectrograms of penumbrae of some sunspots it is concluded that the maximum magnetic field strength occurs in dark filaments and amounts to 1800-1900 G; the intensity of the magnetic field in dark filaments is 100-400 G larger than in the neighbouring bright filaments; the bright
