Mag.=16.8U, R.A.= 00 42 44.81 Decl=+41 18 00.9, remotely using a 0.25-m f/3.4 hyperbolic astrograph + unfiltered CCD (SBIG ST-10XME) at the RAS Observatory near Mayhill, NM, U.S.A.(H06). Position and magnitude were measured on an image composed from 3-frames which were taken by each 120-seconds exposure under the limiting magnitude = 18.5. Observer T.
