We present Far Ultraviolet Spectroscopic Explorer ($\it FUSE$) observations of molecular hydrogen (H 2 ) gas observed at a high-velocity of $V_{\rm LSR} = +66$ km s -1 towards the star HD 47240 which lies just behind the Monoceros Loop Supernova Remnant at a distance of ~1800 pc. These absorption features have been detected in six lines of the $J = 3$ rotational level, with an equivalent molecular hydrogen column density of log $N({\rm H}_{2}) = 14.10, \pm\,0.12$ cm -2 . The observed data are best fit with a single excitation temperature, T ex , of ~1000 K, which when comparised to temperatures generally found for low J -levels is unusually high for interstellar H 2 . The molecular fraction in this HV cloud has a very low value of log $f = -4.5\pm0.25$, which is similar to that found for HV clouds in the galactic halo.
