✦ Synopsis

Tsallis [Physica A 340 (2004) 1) identified a set of numbers, the ''q-triplet'' {q stat , q sen , q rel }, for a system described by non-extensive statistical mechanics. The deviation of the q's from unity is a measure of the departure from thermodynamic equilibrium. We present observations of the q-triplets derived from two sets of daily averages of the magnetic field strength B observed by Voyager 1 in the solar wind near 40 A.U. during 1989 and near 85 A.U.
