The transient approximately located at R.A.=00h42m52.32s +41d16'12".8 (equinox 2000.0). Which is about 90.2" east and 4.3" north of the center of the NGC224(M31). Nothing is visible at this position on archival images taken on Jan. 27.67588 UT(limiting mag 19.0). It was suspected the recurrent nova RN M31N 1926-07c.
