Mi Zhang and Xing Gao
Mi Zhang and Xing Gao, report the discovery of a possible nova (mag approximately 19.5) on severl 300-s survey images (limiting mag about 20.5) taken by Xing Gao in Xingming Observatory Sky Survey(C42) around Jan. 23.53175 UT using a unfiltered CCD ( + 0.6-m f/8 Ritchey-Chretien telescope ). The transient approximately located at R.A.=00h43m00.08s +41d18'34".0 (equinox 2000.0). Which is about 177.7" east and 145.5" north of the center of the NGC224(M31). Nothing is visible at this position on archival images taken on Jan. 20.53300 UT(limiting mag 20.0). NET UCAC-4 XM08MZ C2019 01 23.53175 00 43 00.08 +41 18 34.0 19.5V C42 All images can be seen from:
