| Abstract: | The high angular resolution and image stability of the HINODE Solar Optical Telescope allows its spectro-polarimeter to measure polarization in the 630 nm Fe~{\sc{i}} lines to very high precision and at high angular resolution. We find a dynamic horizontal component to the magnetic field of the very quiet Sun (internetwork) with apparent flux densities much larger than that of the vertical component. More than 50\% of the internetwork is covered by horizontal fields with average apparent flux density of 70 Mx/cm$^2$, whereas the average internetwork vertical flux density is of order 10 Mx/cm$^2$. The orientation of the horizontal flux is random, and evolves on times and at spatial scales typical of granulation. This flux may be the source of the ``seething’’ horizontal flux reported recently by Harvey, et al.\ (ApJ Letters, in press), and might also give rise to the Hanle depolarization of resonance scattering that indirectly supported the presence of a hidden turbulent flux. |
