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
