First Ultraviolet Observations of the Optical Couterpart of the X-Ray Source 2S0114+650

Abstract

The X-Ray Source 2S0114+650 discovered by SAS-3 in 1978 has been associated with a highly reddened star showing broad H_α emission. We observed this star with the LWR spectrograph on board the I.U.E. Satellite on Sep. 1980 and Feb. 1981. An Ultraviolet flux was detected longward of the 2200 Å 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 2200Å seems to deviate from the standard interstellar extinction law.
