M. ; Tarbell, T. D. ; Topka, K. P. Abstract Narrow-band observations of a solar emerging-flux region, obtained at 525.02 nm with resolution 0.5 arcsec using the Sacramento Peak vacuum-tower telescope and the Spacelab 2 tunable filter on December 10, 1979, are reported. The data are presented in histograms and characterized in detail. Magnetic-flux concentrations of 600-1000 G are found to be located in areas of suppressed downflow near holes or pores in the granulation pattern, while 100-500-G concentrations occur in areas with stronger downdrafts, in cell-like structures of diameter 2-5 arcsec, the fields being aligned with dark intergranular lanes. It is inferred that granulation concentrates the magnetic field in the downflow lanes (as found in numerical simulations by Nordlund, 1983), and that the magnetic structures are more diffuse and longer-lasting than the bright spots; thus bright-point maps are contained in, rather than equivalent to, magnetic-field maps.
