We report ALMA Band 9 continuum observations of the normal, dusty star-forming galaxy A1689-zD1 at z = 7.13, resulting in a similar to 4.6 sigma detection at 702GHz. For the first time, these observations probe the far-infrared spectrum shortward of the emission peak of a galaxy in the Epoch of Reionization (EoR). Together with ancillary data from earlier works, we derive the dust temperature, T-d, and mass, M-d, of A1689-zD1 using both traditional modified blackbody spectral energy density fitting, and a new method that relies only on the [CII] 158 mu m line and underlying continuum data. The two methods give T-d = (42(-7)(+13), 40(-7)(+13))K, and M-d = (1.7(-7)(+13), 2.0(-7)(+13)). Band 9 observations improve the accuracy of the dust temperature (mass) estimate by similar to 50 per cent (6 times). The derived temperatures confirm the reported increasing T-d-redshift trend between z = 0 and 8; the dust mass is consistent with a supernova origin. Although A1689-zD1 is a normal UV-selected galaxy, our results, implying that similar to 85 per cent of its star-formation rate is obscured, underline the non-negligible effects of dust in EoR galaxies.
