The GSFC Cosmic X-ray Spectroscopy experiment on OSO-8 observed a weak galactic X-ray source near l/sub i//sub i/approx. =288degree, b/sub i//sub i/ approx. =-1degree for three days during 1975 July. The spectrum for this source between 2 and 20 keV is well represented by a thermal spectrum of kT =7.34 (+3.6, -2.6) keV with an intense iron emission line centered at 6.5 +- 0.2 keV. However, a power-law continuum cannot be ruled out. The error box in the Uhuru source 4U 1043--59, the only known X-ray source in our field of view, contains the radio supernova remnant G287.8--0.5. The possible association of the X-ray source with this supernova remnant is discussed. (AIP)
