Abstract Ariel VI observations of Cygnus X-2 have revealed a rather flat spectrum between 0.1 and 1.5 keV with variable emission at low energy. Of the two conflicting interpretations of this object in terms of i) a distant high-luminosity (Lx ∼ 1038 ergs s−1) binary and ii) a nearby low-luminosity (Lx ∼ 1035 ergs s−1) degenerate dwarf system, our measurements support the latter.
