Pérez-Ramírez (Univ. de Jaén), report:\n\n\"Following the detection by Swift of GRB 090423 (Krimn et al. GCNC \n9198), millimeter observations were conducted on Apr 23 & 24 at the \nPlateau de Bure Interferometer. Consistent with the nIR afterglow \n(Tanvir et al. GCNC 9202) we clearly detect a source at 3-mm with a flux \ndensity of ~0.2 mJy (preliminary) on the combined dataset. Pending of \nconfirming its variability we propose this as the likely millimeter \nafterglow  to GRB 090423. Considering the reported redshift values \naround z ~ 8, this is the most distant radio source detected to date.  \nFurther observations are scheduled. We acknowledge the Bure staff for \nits excellent support.\"",
