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 Hα 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.
