The transient (mag approximately 17.9) on one 40-s survey image (limiting mag about 19.5) taken by Xing Gao in Xingming Observatory Sky Survey(C42) around Dec. 13.80951, 2017, using a unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=356-mm @f/6.9 ). The new object approximately located at R.A.=02h29m49.53s +45d46'51".4 (equinox 2000.0). Which is about 7.7" east and 18.5" north of the center of the 2MASX J02294877+4546331. Nothing is visible at this position on archival image taken on Nov. 09.62782, 2017 (limiting mag 19.5). All images can be seen from:http://www.xjltp.com/XOSS/PSP17G/PSP17G.htm
