Guoyou Sun, Wenzhou, Zhejiang, China; and Xing Gao, Urumqi, Xinjiang, China, report the discovery of a possible nova at mag approximately 18.5 on several 60-s unfiltered survey images (limiting mag about 19.5) taken by Xing Gao in the course of the Xingming Observatory Sky Survey around Oct. 29.587 UT using a Celestron C14 Schmidt-Cassegrain telescope at Mt. Nanshan. The new object is approximately located at R.A. = 0:42:36.97, Decl. = +41:19:28.7 (equinox 2000.0), which is about 110" west and 200" north of the center of NGC 224 = M31. Nothing is visible at this position on archival images taken on Oct. 26.536 (limiting mag 19.0), Oct. 27.602 (limiting mag 19.5), or Oct. 28.661 (limiting mag 19.5).
