We detected a radio\nsource with a preliminary flux density of ~0.4 mJy at a central\nfrequency of 17 GHz at\n\nRA = 13:25:28.48\nDec = -32:25:32.14\n              \nwith positional uncertainty of ~1.5 arcsec. The position of the radio\nsource is consistent with the candidate optical (de Wet et al., GCN\nCirc. 32289) and X-ray afterglow (Gropp et al., GCN Circ. 32296)\npositions. \n\nFurther observations with several facilities at different frequencies\nare ongoing.\n\nWe thank CSIRO staff for rapidly scheduling and supporting these\nobservations.",
