We have analyzed a pair of Suzaku XIS1 spectra of the soft X-ray background, obtained by observing towards and to the side of a nearby (d = 230 pc) absorbing filament in the southern Galactic hemisphere. We fit multicomponent spectral models to the spectra in order to separate the foreground emission due to the Local Bubble (LB) from the background emission due to the Galactic halo and unresolved AGN. We obtain LB and halo parameters that are different from those obtained from our analysis of XMM-Newton spectra from these same directions. The LB temperature is lower (log T = 5.93 versus 6.06), and the flux due to the LB in the Suzaku band is an order of magnitude less than is expected from our XMM-Newton analysis. The halo components, meanwhile, are hotter than previously determined, implying our Suzaku spectra are harder than our XMM-Newton spectra.
