(*E*(*B-V*)) map, made from the Schlegel, Finkbeiner and Davis (henceforth SFD) Dust Survey [@sch98], shows a strong anti-correlation with the soft X-ray emission image [@jo11]. Recent spectroscopic observations made in the FUV revealed the existence of and \* emission lines as well as molecular fluorescence H$_2$ lines, implying that the OES is truly a multi-phase object, consisting of hot gases and cold dust that interact with each other [@kre06; @ryu06; @ryu08; @jo11].

The dust properties of the OES region have not been explored well because of the lack of sufficient diffuse FUV observations. Based on the data available from the Voyager measurement, @mur93 suggested a lower limit of $\sim$0.3 for the albedo assuming isotropic scattering, and an upper limit of $\sim$0.8 for the phase function asymmetry factor with perfectly reflecting grains. However, it should be noted that the Voyager observations provided limited information, and only for two regions with a field of view of 0$^\circ$.10 $\times$ 0$^\circ$.87 and a spectral band of 38 [Å]{}. In this paper, we report the results of our study on the dust scattering properties of the OES region. We performed Monte Carlo simulations and compared the results with the diffuse emission map made from the
