J.-j. Zhang, Y.-f. Fan, LiJiang Observatory, confirmed this object on one 90-s survey image (limiting mag about 20.0) taken by Yufeng Fan around Mar 17.5131 UT using a R-band CCD with 2.4-m telescope (+ YFOSC) at the LiJiang Observatory of YNAO. End figures for astrometry were AR. 04.75s DEC. 40.2", Mag. 17.0 R(equinox 2000.0, USNO-A2.0 stars).
