The OT was seen in 4 images. There is no minor planet at this place. We have reference image without OT on 2015-09-16.92046 UT with unfiltered magnitude limit 20.0m. There is no any known sources inside 5" in VIZIER database, that means 22m POSS limit in history and more then 4.7m of current outburst amplitude. We reobserved it in MASTER-Kislovodsk on 2017-08-20 20:35:51.304 UT with unfiltered m_OT=17.4 That means not optical GRB counterpart, but possible CV (UG?) nature. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/210141.71232638.9.png
