The observation was done with the R-band filter beginning\nat 2018-12-01 10:56:18 UT (8.3 hours after the INTEGRAL trigger) for\n300 sec. At the position of the Swift X-ray afterglow (Mereghetti et\nal. GCN 23471; Page et al. GCN 23474), an optical transient is clearly\ndetected with a R magnitude of 16.68 +/- 0.03 by comparing with the\nUSNO-B1 catalogue. The position is also consistent with the optical\ntransient detected by Podesta et al. (GCN 23470) 18 sec after the\ntrigger. Given the fading of the optical brightness, this transient is\nthe optical afterglow of GRB 181201A.",
