We perform a statistical study of 40 crossings of the current sheet when the three spacecraft THB, THC, and THD were distributed along the tail in the vicinity of midnight with coordinates X-B is an element of [-30 R-E, -20 R-E], X-C is an element of [-20 R-E, -15 R-E], and XD similar to -10 R-E. We obtain profiles of the average electron temperature < T-e > and the average magnetic field < B-z > along the tail. Electron temperature and < B-z > increase towards the Earth with almost the same rates (i.e., ratio < T-e > / < B-z > approximate to 2 keV/7 nT is approximately constant along the tail). We also use statistics of 102 crossings of the current sheet from THB and THC to estimate dependence of T-e and B-z distributions on geomagnetic activity. The ratio < T-e > / < B-z > depends on geomagnetic activity only slightly. Additionally we demonstrate that anisotropy of the electron temperature < T-parallel to/ T-perpendicular to > approximate to 1.1 is almost constant along the tail for X is an element of [-30 R-E, -10 R-E].
