Iceland) report on behalf of a larger\ncollaboration:\n\nWe observed the field of GRB 141109A (D'Avanzo et al., GCN Circ. 17037)\nwith the 2.5-m Nordic Optical Telescope (NOT) with ALFOSC starting at 04:39\nUT on 10-Nov-2014.  We obtained 3x300 s frames in the SDSS r-band filter.\n\nWe clearly detect the optical afterglow of GRB 141109A (Covino, GCN Circ.\n17039; Xu et al., GCN Circ. 17040; Graham et al., GCN Circ. 17041; Im et\nal., GCN Circ. 17042; Xin et al., GCN Circ. 17053), which has an apparent\nmagnitude of r=22.1 +- 0.1 at a mid exposure time of +22.8 hr.  The\nmagnitude is not corrected for foreground extinction, and is calibrated\nusing several nearby SDSS stars in the FOV.���",
