TITLE: GCN CIRCULAR NUMBER: 23739 SUBJECT: GRB 190114A: NOEMA detection of the mm afterglow DATE: 19/01/16 14:51:27 GMT FROM: Antonio de Ugarte Postigo at IAA-CSIC A. de Ugarte Postigo (HETH/IAA-CSIC and DARK/NBI), M. Bremer, O. Feher (both IRAM), S. Schulze (Weizmann), C. C. Thoene, L. Izzo, D. A. Kann, M. Blazek, K. Bensch (all HETH/IAA-CSIC), D. A. Perley (LJMU), S. Martin (ALMA), I. de Gregorio-Monsalvo (ESO), M. Michalowski (AOI-AMU), D. B. Malesani (DARK/NBI, DAWN/NBI) R. Sanchez-Ramirez (INAF-IAPS) report: We observed the afterglow of GRB 190114A (LaPorte et al., GCN 23677, Siegel et al. GCN 23678), at a redshift of z = 3.3765 (de Ugarte Postigo et al. GCN 23680) with NOEMA at 76, 92, 136 and 152 GHz. Observations started at 21:02 UT on 15 January, 42 hrs after the GRB. The afterglow is well detected at all frequencies and had a flux density of 0.9 mJy at 92 GHz. We derive the following refined coordinates for the afterglow: R.A.(J2000): 04:22:10.58 Dec.(J2000): +02:11:28.4 with an error of +/- 0.1" Further follow-up observations are encouraged
