Stecklum (both Thueringer Landessternwarte Tautenburg) \nreport:\n\nWe imaged the field of GRB 161129A (Kocevski et al., GCN 20210) with the \nTautenburg Schmidt telescope equipped with the prime focus CCD camera. \nObservations were performed at a midtime of 16:41 UT (November 29).\n\nInside the enhanced XRT error circle (radius 1.7 arcsec; Beardmore et al., \nGCN 20211) we find a faint source at coordinates RA, Decl. (J2000) = \n21:04:54.53, 32:08:05.9 (+/- 0.5 arcsec). Using the USNO B2 star at \ncoordinates RA, Decl. (J2000) = 21:04:54.65, 32:08:05.6 as a photometric \nreference (Ic = 18.38), we measure for this source a preliminary (Vega) \nmagnitude of Ic = 20.3 +/- 0.2 mag.\n\nWe note, however, that the DSS2 red shows a faint source at the central \nposition of the enhanced XRT error circle at roughly the same coordinates. \nGiven that the seeing in our images is about 2 arcsec, and given that our \nimages are not substantially deeper than the DSS2 red, we cannot decide \nwhether we see this faint source or a faint transient on top of it. In any \ncase, at the time of our observations any optical transient was fainter \nthan about Ic=20.",
