Description
High-resolution G-band images of the interior of a supergranulation cell
show ubiquitous bright points (BPs; some 0.3 BPs per Mm2).
They are located in intergranular lanes and often form chains of
elongated blobs whose smallest dimension is at the resolution limit (135
km on the Sun). Most of them live for a few minutes, having peak
intensities from 0.8 to 1.8 times the mean photospheric intensity. These
BPs are probably tracing intense magnetic concentrations, whose
existence has been inferred in spectropolarimetric measurements. Our
finding provides a new convenient tool for the study of the internetwork
magnetism, so far restricted to the interpretation of weak polarimetric
signals.
