Martinez-Osorio (NOT) report on behalf of a\nlarger collaboration:\n\nWe observed the BAT field of GRB 130829A (Grupe et al., GCN 15131)\nusing the 2.5 Nordic Optical Telescope (NOT) equipped with StanCam. We\nobtained 4x300s R-band frames at a mean time of 20:46 UT on\n2013-08-29, i.e., 15.05 hr after the BAT trigger. Observations were\ncarried out at high airmass, and the resulting seeing was about 1\narcsec. Our images cover 96% of the BAT error circle.\n\nOur image reaches a depth comparable to the SDSS, roughly R = 22.7.\nVisual comparison between our data and the SDSS image reveals no new\nsource within the BAT error circle.",
