Abstract: We have modelled diffuse far-ultraviolet (FUV) spectrum observed by the Far Ultraviolet Spectroscopic Explorer (FUSE) near M42 as the scattering of the starlight from the Trapezium stars by dust in front of the nebula. The dust grains are known to be anomalous in Orion with RV= 5.5 and these are the first measurements of the FUV optical properties of the grains outside of `normal' Milky Way dust. We find an albedo varying from 0.3 +/- 0.1 at 912 Å to 0.5 +/- 0.2 at 1020 Åwhich is consistent with theoretical predictions
