Turku), R. Salinas\n(FINCA) report on behalf of a larger collaboration:\n\nWe observed the field of GRB 130606A (Ukwatta et al., GCN 14781) using\nthe 2.5m Nordic Optical Telescope (NOT) equipped with the MOSCA\nimager. Observations started at 21:35 UT on 2013-06-06 (i.e., 0.5 hr\nafter the burst) and 2x300 s frames were obtained in the Sloan\nr-filter.\n\nClose to the refined XRT position, we detect an object not visible in\nthe DSS and SDSS images of the field, at the following coordinates:\n\nRA (J2000) = 16:37:35.188\nDec(J2000) = +29:47:47.03\n\nThese coordinates are formally outside the XRT error circle, which is\nhowever affected by extra systematic uncertainties due to the problems\nin the satellite attitude (Ukwatta et al., GCN 14781). The object has\nm(r) = 20.8, calibrated against the SDSS.\n\nWe suggest this object is the afterglow of GRB 130606A. It is probably\nthe same object reported by Jelinek et al. (GCN 14782).",
