  The thermal fluctuation level of the Weibel instability is recalculated. It
is shown that the divergence of the fluctuations at long wavelengths, i.e. the
Weibel infrared catastrophe, never occurs. At large wavelengths the thermal
fluctuation level is terminated by the presence of even the smallest available
stable thermal anisotropy. Weibel fields penetrate only one skin depth into the
plasma. When excited inside, they cause layers of antiparallel fields of skin
depth width and vortices which may be subject to reconnection.
