Abstract

High-quality photographs of the quiet and enhanced network have been obtained at the centre of Fe i λ6569.2 and in the nearby continuum, using a 1/8 Å filter. In agreement with Dunn and Zirker, the photospheric granules are noticeably smeared in the neighbourhood of the enhanced network. Nevertheless, many of the bright network elements are co-spatial with individual (smeared) photospheric granules.

The photospheric granulation fails to appear at the centre of the Fe line, suggesting that the top of the convection zone is located below the temperature minimum.
