Measurements of the soft X-ray background intensity show that the intensity is largest in that part of the sky where the columnar atomic hydrogen density is smallest. In the direction bII =-60°, lII = 10° the intensity is found to be 195 ± 20 photons cm−2 sec−1 ster−1 keV−1 near 0.26 keV and 20 ± 3 photons cm−1 sec−1 ster−1 keV−1 near 0.9 keV. The intensity in the galactic plane is unexpectedly large.
