Abstract
The interaction between small-scale magnetic fields and horizontal photospheric flows has been studied from observations of high angular resolution\(( \sim \tfrac{1}{4}arc\sec )\) obtained with the Lockheed narrowband filter in the Swedish Vacuum Solar Telescope at La Palma. The measured magnetic flux density (αB ‖) is in the range from a detection limit of ≈ 10 G to about 500 G, showing a good correspondence with the filigree. The magnetic flux elements take part in the local flows towards downdrafts at the supergranulation cell boundaries. The measured flux density, as well as the associated filigree intensity, decrease as the structures approach the downdrafts, presumably as a result of increased tilting and possibly submergence of flux into the downdrafts.
