  We analyze Fe I 630 nm observations of the quiet Sun at disk center taken
with the spectropolarimeter of the Solar Optical Telescope aboard the Hinode
satellite. A significant fraction of the scanned area, including granules,
turns out to be covered by magnetic fields. We derive field strength and
inclination probability density functions from a Milne-Eddington inversion of
the observed Stokes profiles. They show that the internetwork consists of very
inclined, hG fields. As expected, network areas exhibit a predominance of kG
field concentrations. The high spatial resolution of Hinode's
spectropolarimetric measurements brings to an agreement the results obtained
from the analysis of visible and near-infrared lines.
