We have observed the pulsating X-ray source Cen X-3 in the energy range 0.37-6.9 keV. The source is found to cmit soft X-rays below 2 keV as bright as in the range 2-6 keV. The observed energy spectrum can be interpreted as the thermal bremsstrahlung spectrum of the compact X-ray source modified by absorption in a highly ionized circumstellar envelope. (auth)
