F/5.5 + Starlight X-Press Trius SX9 CCD camera on several unfiltered images, 35 sec. exposure, mag. about+ 18.0,limit mag. about+ 19.0. (the new object is located at: R.A. 09 14 55.30, DECL. +46 54 09.0 (2000.0). My past image of the same field taken on 2018/02/08.83 showed nothing at that position (limit mag.+ 19.0) and it doesn't appear on P.O.S.S. II red and blue plates. No known minor planet is marked in that position for the time of the discovery. Mag. values from: GSC and USNO.
