[en] Observations from the UCSD OSO-7 experiment show Cen A had a hard E^-1.² number spectrum during 1972 July--August and 1973 March. Our data indicate a 230 percent increase in the 10--100 keV flux from 1.99 +- 0.41 x 10^-2 counts cm^-2 s^-1 to 4.64 +- 1.13 x 10^-2 counts cm^-2 s^-1 between these observations. The 1972 July--August data give a 10--100 keV flux of approx.4 x 10⁴² ergs s^-1 if dapprox.5 Mpc. The data are equally consistent with various Compton-synchrotron models or with a T>200 keV thermal-bremsstrahlung model with cutoff energy less than 4 keV
