Observations\n\nstarted about 0.21 days after the burst. A total of 6 images (600s\n\nexposure each) in R band were taken with Nickel telescopes, while\n\nKAIT images were taken in clear band, with 60s exposure and coadded.\n\nWe detected the optical afterglow (Lipunov et al., GCNs 34476, 34477,\n\n34481, 34482; Gompertz et al., GCN 34480; Moskvitin et al., GCN 34483;\n\nMalesani et al., GCN 34485; Siegel and Tohuvavohu, GCN 34486; Pankov\n\net al., GCN 34487; Quadri and Strabla, GCN 34488; Klose et al., GCN\n\n34491; Moskvitin et al., GCN 34495; 34497) and measure the following\n\nmagnitude calibrated to the Pan-STARRS1 catalog:\n\n\n\nt-t0(days) filter mag   err\n\n0.218      clear  21.8  0.3\n\n0.226      R      21.6  0.2\n\n0.324      clear  21.3  0.3\n",
