Observations were performed in the clear\n(roughly R) filter, and the exposure time was 60 s per image.\n\nThe optical afterglow of GRB 170705A (Starling, et al.,GCN 21289;\nLipunov et al., GCN 21291; Butler et al. GCN 21293,\nEmery et al. GCN 21294, Ugarte Postigo et al. GCN 21298, Pozenenko\net al. GCN 21300) was clearly detected in every single image from the\nfirst night and in an image co-added from thirteen frames in the\nsecond night. Preliminary photometry of the afterglow calibrated to\nseveral nearby SDSS stars gives 18.1 +/- 0.2 mag at mean time\n1.66 hours and 20.3 +/- 0.3 mag at mean time 1.08 days.",
