GCNC  16546) was observed in i'-band\nwith  the 10.4m GTC telescope in two epochs centered on July 9.12955 and\n10.10966 UT (1.9 and 25.4 hours post burst). Comparison between those two\nepochs reveals that the optical candidate reported by Castro-Tirado et al.\n(GCNC 16554) has faded by ~0.7 mags (from i'~21.3 to 22.0, both in AB),\nimplying a shallow decay index of ~0.2.  A similar decay is measured in\nz'-band.\n\n[GCN OPS NOTE(12jul14): Per author's request, AG was added to the author list.]",
