Revised Position of the X-ray Source near the Nucleus of M31

We have determined a more accurate position for the x-ray source near the nucleus of M31, based on analysis of new ROSAT HRI observations and re-analysis of earlier ROSAT and Einstein HRI observations of the region. Our revised position is ~ 1.6({'}{'}) south of the nuclear radio source discovered by Crane, Dickel, and Cowan (ApJ, 390, L9) and includes the radio source in its ~ 2({'}{'}) radius, 99% error circle. Given the local x-ray source density, the chance occurrence of an x-ray source brighter than ~ 10(36) erg s(-1) is ~ 2%. Analysis of the superposition of three deep, ROSAT HRI observations also indicates the presence of a previously uncataloged source ~ 17({'}{'}) to the east of the nuclear source.
