The transient approximately located at R.A.=00h43m46.45s +41d33’40”.8 (equinox 2000.0). Which is about 700.5" east and 1052.3" north of the center of the NGC224(M31). Nothing is visible at this position on archival images taken on Feb. 1.57521, 2021 (limiting mag 18.5) . Images can be found at: http://xjltp.china-vo.org/xm50mz.html2021TNSTR.325....1Z
