The 1RXS J180556.1$-$343818 spectrum in the $0.3$-$7$ keV band was explained by X-ray emission originated from an optically-thin thermal plasma with temperatures of $0.5$ and $1.7$ keV. The estimated absorption column density of $N_{\\rm H} \\sim 4 \\times 10^{20}$ cm$^{-2}$ was significantly smaller than the Galactic HI column density towards the source.
