Abstract

A survey of Southern galactic hemisphere was made with a soft X-ray rocket-borne telescope launched on October 27, 1976 from the equatorial station, Thumba (S. India). Three extended regions of diffuse soft X-ray emission in the C-band (0.15-0.5 keV) and M-bands (0.5-1.5 keV) were detected and appear to be coincident with the regions of very low neutral hydrogen column density. Plasma temperatures of a few million degrees are required to explain the X-ray emission from these regions.
