GCN 32191) with the FLAMINGOS-2 spectrograph\nmounted on the Gemini-South telescope. Observations were carried\nout in the Ks filter with a total exposure of 260 s beginning at\n3.7 d post-trigger.\n\nWe detect a faint source within the XRT position (Goad et al. 32192)\nwith magnitude Ks = 20.0+/-0.3 AB mag. The object is located at:\n\nRA, DEC = 04:26:03.56, -37:15:34.97\n\nwith an uncertainty of 0.5\". This source is offset by 6\" and 13\",\nrespectively, from two bright galaxies. The latter is located\nat redshift z~0.049 (Cenko et al. GCN 32191). Further observations\nare planned to determine whether the source is fading or if it\nis dominated by the contribution from an underlying host galaxy.\n\nWe thank the staff of the Gemini Observatory, in particular\nSteve Margheim and Joan Font-Serra, for rapid scheduling of\nthese observations. We thank Rodrigo Carrasco for carrying\nout the observations.",
