[en] We present the first in situ observations of turbulence in the local interstellar magnetic field $\mathit{B}$, measured by Voyager 1 from 2013.36 to 2014.64. The fluctuations of the components of $\mathit{B}$, the rms of the fluctuations of the components of $\mathit{B}$, and magnitude of $\mathit{B}$ have a Kolmogorov $k^{-<!--\; ???\; -->5/3}$ spectrum in the range from $4\times <!--\; ??\; -->{10}^{-<!--\; ???\; -->6}$ to $3\times <!--\; ??\; -->{10}^{-<!--\; ???\; -->7}$ Hz. The turbulence is compressible; the variance is primarily along the average magnetic field. The turbulence is weak, the ratio of the turbulent fluctuations to the average field being 0.023. A small linear increase in the azimuthal angle λ of $\mathit{B}$ and a small linear decrease in the elevation angle δ were observed during the 468 day interval under consideration, which might be related to magnetic draping.
