  Bodeker has recently shown that the high temperature sphaleron rate, which
measures baryon number violation in the hot standard model, receives
logarithmic corrections to its leading parametric behavior; Gamma = kappa'
[log(m_D / g^2 T) + O(1)] (g^2 T^2 / m_D^2) \alpha_W^5 T^4. After discussing
the physical origin of these corrections, I compute the leading log coefficient
numerically; kappa' = 10.8 pm 0.7. The log is fairly small relative to the O(1)
``correction;'' so nonlogarithmic contributions dominate at realistic values of
the coupling.
