GRS 1758-258和1 E 1740.7-2942是两个持续存在的硬X射线源，位于银河系中心周围约100 ° 2的区域。最近发现银河系中心零化子1 E 1740.7-2942与一个紧凑的射电源有关，该射电源发出双射电喷流。在这封信中，我们报告了GRS 1758-258 X射线位置周围场的深6厘米VLA映射结果。我们的观测结果表明，在1 E 1740.7-2942中，存在另一个三重射电源，其中心分量是时变的，并且福尔斯落在ROSAT的误差圆（半径为10″）内
GRS 1758-258 and 1E 1740.7-2942 are two persistent hard X-ray sources in a region of about 100 deg 2 around the Galactic center. The Galactic center annihilator, 1E 1740.7-2942, has recently been found to be associated with a compact radio source from which a double radio jet emanates.In this Letter we report the results of a deep 6 cm VLA mapping of the field around the GRS 1758-258 X-ray position. Our observations reveal, as in 1E 1740.7-2942, the presence of another triple radio source, whose central component is time variable and falls inside the error circle (10″ of radius) of ROSAT
