Abstract
THE discovery of a faint X-ray source with the X-ray detectors on SAS 3 at a location with galactic coordinates lII ∼282°, bII∼−9° is reported here. A subsequent optical search has revealed a likely optical counterpart in the form of a 17th magnitude star with He II 4686 and Hβ in emission. It is, therefore, likely to be a low-luminosity galactic X-ray source.
