Fig. 1


Stokes images of a spectral interval around the Sr I 4607 Å line. The spatial direction spans 47′′ on the solar disk. The observed region was near the est limb at μ ≃ 0.3, and the slit was placed parallel to the nearest limb. The reference direction for positive Stokes Q is the tangent to the nearest solar limb. These images are the result of a 2-minute observation average. The granulation pattern can be recognized in the intensity image, in particular in the continuum. The QI image showsthe scattering polarization peak in the core of the Sr I line. Spatial variations at granular scales of this peak can be observed. Weak UI signals, just above the noise level, can be observed in the core of the Sr I line. In VI the typical antisymmetric Zeeman patterns can be easily recognized. Note in particular some small sized VI structures (for instance at spatial position 27′′).
