   We propose to observe the northern middle lobe of the nearby radio
   galaxy Centaurus A.  The previous ASCA short term (6ks) observation
   result fromthe target suggests of a diffuse non-thermal emission from
   the lobe. We are aiming to reveal the emission mechanism with this
   follow up observation.  If the X-ray emission arise via inverse-Compton
   scattering of the cosmic microwave background photons as we see in a
   number of radio lobes, we will be measure the energy densities of
   magnetic field and electrons in thelobe, to see energy distributions
   towards the outer lobe which we have observed with ASCA and Beppo-SAX.
