The object approximately 17.7 CV on several 120-s survey images (limiting mag about 19.0) taken by Xing Gao in Xingming Observatory #2 (N89) around 2022 Mar. 05.59237 UT using a unfiltered CCD (0.5-m f/4 reflector). The transient approximately located at R.A. = 00h44m10.72s, Dec. = +41d54'22.4" (equinox 2000.0). Which is about 974.0" east and 2294.9" north of the center of the NGC224(M31). Nothing is visible at this position on archival images taken on 2022 Mar. 02.61067 UT (limiting mag 18.5). Images can be found at: http://xjltp.china-vo.org/psp22p.html .2022TNSTR.790....1Z
