[en] Three proportional counters with window film thickness of 0.96, 1.53 and 4.3 μm were used for the observation of North Polar Spur. The soft X-ray energy regions observed were the L-band (0.14 - 0.38 keV) and M-band (0.5 - 1.0 keV). The energy spectrum seems to be interpreted in terms of the X-ray emission from thin hot plasma. The present data indicate that the plasma consists of two components with temperature from 1 to 2 x 10⁶ deg K and of 5 x 10⁶ deg K. In the range from 0.4 to 1 keV, the emission lines of C-5, C-6, N-6, N-7, O-7, O-8, Fe-17 and Ne-9 contribute to the soft X-ray spectrum. The low temperature component is explained from heating by the shock wave generated by supernova explosion, and the high temperature component is explained as the emission from heated intercloud gas.
