Aceituno \n(IAA-CSIC) report:\n\nWe observed the optical afterglow of GRB 190114A (Siegel & LaPorte, GCN \n#23678), detected by Swift (LaPorte et al., GCN #23677), with the T150 \ntelescope of the Sierra Nevada Observatory (OSN). We obtained 5 x 360 s \nimages in the Ic band at 16.98 hours after the GRB. The afterglow is \nwell-detected in each single image.\n\nDays\tIc mag\terror\n\n0.7075\t20.41\t0.10\n\nMagnitudes are given in the AB system. They were measured vs. four \nPan-STARRS comparison stars, using the transformation equations of \nLupton (2005), and transformed back into AB mags.",
