Barentine (APO), R. McMillan (APO), B. Ketzeback (APO), and D. Reichart (North Carolina) report on behalf of the ARC GRB team of the FUN GRB collaboration: We began observations of the localization of GRB 050713 (Falcone et al., GCN 3525) with NIC-FPS on the 3.5m ARC at APO beginning 53 min after the burst. We detect all three of the candidates identified by Malesani et al. (GCN 3582) in J,H,Ks in 80-sec integrations, and identify their first candidate as fading. NIC-FPS is currently in its commissioning phase. This message may be cited.
