The X-ray binary GX 1+4 has been observed with ROSAT three days after a high state which lasted about three weeks. An accurate position R.A.(2000) = 17h 32m 2.1s, Dec.(2000) = -24 deg 44 min 44 sec has been derived. This confirms the optical identification with the symbiotic star V2116 Oph. Although the intensity of the source was not sufficient to establish a reliable spectrum, the pulse height spectrum is consistent with a highly absorbed source (NH = 5.5 x 1022/sq cm, as measured with GINGA). Assuming a thermal spectrum with kT = 50 keV we derived a luminosity within 0.1-2.4 keV: Fx = 1.4 x 1035 erg/s/sq cm. GX 1+4 is surrounded by a faint, diffuse emission. We discuss possible implications for the distance of the source if this halo is interpreted as radiation scattered on interstellar dust grains.
