Title: The internetwork magnetic field at the THEMIS resolution limit
Authors: V. Bommier, E. Landi Degl'Innocenti, G. Molodij
Form: poster
Abstract: Recent UNNOFIT inversion of THEMIS observations has revealed that the observed turbulent nature (i.e., with a pixel to pixel varying direction) of the internetwork field is of solar origin (Bommier, V., Landi Degl'Innocenti, E., Landolfi, M., Molodij, G. 2007, A\&A, 464, 323). Further observations of the spatial and temporal correlation lead to the conclusion that the spatial correlation length of this turbulence is of the order of half of a THEMIS pixel, i.e. 0.45 arcsec for these observations. As for the temporal correlation the situation is more complex. These observations will be presented and discussed.
