We propose a Maxwellian-type initial density matrix for a quantum particle placed in an Ohmic environment. The resulting positional Brownian variance is analytically separated into a classical contribution of Chandrasekhar, and a quantum correction term depending upon \ensuremath{\Elzxh} and the input width. \textcopyright{} 1996 The American Physical Society.
