The OT unfiltered magnitude is 17.2m (mlim=17.4m). The OT is seen in 2 images(2019-04-24 03:19:04,03:10:05). There is no minor planet at this place. We have nearest in time reference image without OT at 2019-02-20 06:10:38UT with 17.8 unfilt. magnitude limit There is no any sources in VIZIER database, it means 22m POSS limit and more then5.2 of current outburst amplitude value. Spectral observations are required. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/111505.12-681439.8.png
