The transient approximately located at R.A.=00h47m32.56s +39d38’10”.2 (equinox 2000.0). Which is about 3249.8" east and 5878.3" south of the center of the NGC224(M31). Nothing is visible at this position on archival images taken on Oct. 21.79247 (limiting mag 17.5). Images can be found at: http://xjltp.china-vo.org/psp21ac.html 2021TNSTR3636....1T N
