The transient approximately located at R.A.=00h42m38.07s +41d08’42”.3 (equinox 2000.0). Which is about 70.5″ west and 446.2″ south of the center of the NGC224(M31). Nothing is visible at this position on archival images taken on Jun. 28.83559 (limiting mag 19.0) . Possible the recurrent nova M31 1923-12c (=2012-01b).
