Our measurements were obtained with PACS on board the \\emph{Herschel} satellite at $100~\\mathrm{\\mu m}$ and $160~\\mathrm{\\mu m}$. While the warm dust in the Galactic Centre is too bright to allow for a direct detection of Sgr~A*, we measure a significant and simultaneous variation of its flux of $\\Delta F_{\\nu\\widehat{=}160 ~\\mathrm{\\mu m}} = (0.27\\pm0.06)~\\mathrm{Jy}$ and $\\Delta F_{\\nu\\widehat{=}100 ~\\mathrm{\\mu m}}= (0.16\\pm0.10)~\\mathrm{Jy}$ during one observation.
