Scientific paper

The X-ray source 2S0114+650 discovered by SAS-3 in 1978 has been associated with a highly reddened star showing broad H-alpha emission. The star was observed with the LWR spectrograph on board the IUE satellite in September 1980 and February 1981. An ultraviolet flux was detected longward of the 2200 A bump, consistent with the B0.5 spectral classification and the values of V = 11 and E(B-V) = 1.48. The UV extinction in the region around 2200 A seems to deviate from the standard interstellar extinction law.
