Recent measurements of the low energy diffuse cosmic X-radiation are reported. The results indicate that the large flux observed below 1 keV is inconsistent with an extrapolation of the power law spectrum observed above 2 keV. While the radiation between 2 and 10 keV appears largely isotropic, at least to the limits of resolution of the detector, the 0.27 keV radiation shows significant asymmetry with respect to galactic latitude.
