An improved position for the compact X-ray source in the center of the young supernova remnant RCW 103 is presented. Only one star brighter than V of about 22 mag lies inside the new error circle, but a spectroscopic study of the star rules out any relationship to the X-ray source. A sensitive search for radio pulsations from RCW 103 has proved equally unsuccessful. The absence of an optical or radio counterpart for the central X-ray source strengthens the likelihood that the object is a hot neutron star emitting blackbody radiation. This result is in accord with several theoretical calculations of neutron star cooling rates.
