Iceland) report on behalf of a larger \ncollaboration.\n\nWe observed again the optical counterpart of GRB 160117B (Sonbas et al., \nGCN 18875), using the NOT equipped with the AlFOSC camera. Our \nobservation was carried out in the R band and was composed of 4x300 s \nexposures, with mean time January 19.10 UT (1.52 days after the GRB).\n\nCompared to our previous observation (Malesani et al., GCN 18884), we \nfind a decay slope alpha = 1.10 +- 0.05 (assuming a single power-law \ndecay F propto t^-alpha). This decay is steeper than what reported at \nearly time by Kruehler et al. (GCN 18878).",
