Abstract

Soft X-rays (0.2-1.0 keV) have been detected from the high galactic latitude source MX 2140-60 in a rocket experiment. The measured flux of ~10−10 erg cm−2 s−1 combined with OSO-7 measurements in 2-40 keV X-rays, are best fit by a power law photon spectrum with spectral index 2.3 and a neutral hydrogen column density NH=(3-7) 1020 atoms cm−2. The observations support the source identification with the cluster of galaxies SC 2146-594, as suggested by Lugger.
