C.D. Lee, Y. Urata (NCU), K.Y. Huang (ASIAA) on behalf of EAFON: "We imaged the field of GRB 121108A (Ukwatta et al. GCN 13952) with the Triple Range Imager and POLarimeter 2 (TRIPOL2) attached to the Lulin 1m telescope. The simultaneous three color observations were started on 2012-11-08 20:12:18.2 UT (~2.41 hrs after the burst). There is no new sources in the error region of the X-ray afterglow reported by Ukwatta et al. (GCN 13952) with three sigma limits of g~20.6, r~20.5 and i~20.2 mag (at 2.92 hrs after the burst)."
