OSO-7 Observations of a High-Latitude X-Ray Source Associated with Abell Cluster A2052

An X-ray source with a flux of 1.6 X 1(h1O ergs s-l (2-10 keV) has been observed at high galactic latitude by the MIT X-ray detectors on the OSO-7 satellite. Designated GX 8+50, its position is a = , - `, with a 90 percent confidence error circle of area 0.5 deg2. The data are consistent with a power-law spectrum with a = 1.2 + 0.2 or a thermal-bremsstrahlung spectrum with kT = 4 + 1 keV. A likely identification is the Abell cluster A2052, whose center coincides with the radio source 3C 317. Subject headings: galaxies, clusters of - X-Ray Sources
