XTE J1739-302

R. M. Hjellming, National Radio Astronomy Observatory, reports: "Very Large Array observations on Sept. 26, 30 and Oct. 1 show two candidate radio sources inside and one on the edge of the error region for XTE J1739-302 (cf. IAUC 6748). Positions are: source A, R.A. = 17h38m57s.8, Decl. = -30d08'43" (equinox 2000.0, uncertainties 0s.1 and 2"); source B, 17h38m52s.2s, -30d09'01"; source C, 17h39m00s.6, -30d11'35". Sources A and C have not shown significant variations about fluxes of 4.2 and 4.5 mJy at 4.86 and 8.46 GHz; however, source B may have varied between 9 and 12 mJy at 4.86 GHz from Sept. 26 to Oct. 1, and between 4 and 8 mJy at 8.46 GHz from Sept. 30 to Oct. 1. On this basis source B is the most likely candidate for the radio counterpart of XTE J1739-302. Further observations continue to determine the variability characteristics of these sources."
