Iceland) report on behalf of a larger collaboration:\n\nWe observed the field of GRB 151001A (Swift trigger 657286, Stamatikos \net al., GCN Circ. 18373) with the 2.5-m Nordic Optical Telescope (NOT) \nequipped with ALFOSC on the evening of 01-Oct-2015 between 19:55-20:24 \nUT (5 hr after the burst). In SDSS filters r and g we clearly detect the \noptical afterglow of GRB 151001A at the position given by UVOT \n(Stamatikos et al., GCN Circ. 18373). We derive AB magnitudes of\n\ng = 22.18 +/- 0.05\nr = 21.51 +/- 0.08\n\ncalibrated against SDSS field stars. The g-r color of the afterglow is \nrelatively red compared to typical afterglows.",
