The transient approximately located at R.A.=00h42m04.24s +40d42’33”.6 (equinox 2000.0). Which is about 451.9" west and 2014.9" south of the center of the NGC224(M31). Nothing is visible at this position on archival images taken on Feb. 12.64922, 2021 (limiting mag 19.5) . Images can be found at: http://xjltp.china-vo.org/xm51mz.html
