R. M. Hjellming, National Radio Astronomy Observatory (NRAO); A. J. Mioduszewski, Joint Institute for VLBI in Europe and NRAO; and M. P. Rupen, NRAO, report: "On May 10.49 UT, a radio source was observed with the Very Large Array in the field of the x-ray transient XTE J1806-246 at R.A. = 18h06m50s.72 +/- 0s.04, Decl. = -24o35'28".6 +/- 0".8 (equinox 2000.0). This radio source is well within the error region for the RXTE PCA position reported on IAUC 6891. On May 10.49 the radio source had flux densities of 0.8 +/- 0.3 and 0.8 +/- 0.2 mJy at 1.43 and 4.86 GHz, respectively. It was not present on May 3 and 6, with upper limits of 0.3 mJy at the same frequencies. This variability makes the source a candidate for the radio counterpart of XTE J1806-246."
