Abstract
The first spectral analaysis of GX5-1 is presented, with the source located on the horizontal coordinate axis in the hardness-intensity diagram. It is clear that on all intensity levels two spectral components are necessary to describe the x ray spectra. The first component is always a black body spectrum with a temperature of RT = 1keV approximately. The second component is well depicted by different spectral functions. Intensity variations are caused by intensity changes of black body components, while temperature variations are few. An examination of possible optic candidates for GX5-1 showed that none of them represent a good optic picture of x ray source. EXOSAT data collected by observation of a Gamma-ray burst-source were analyzed; EXOSAT did not discover a burst, perhaps because optic flashes and Gamma-ray bursts are different pictures of a phenomenon.
