POSSIBLE NOVA IN M31
Xinyu Jiang,Guoyou Sun, Mi Zhang and Xing Gao, report the discovery of a possible nova (mag approximately 17.4) on several 40s surveyimages (limiting mag about 19.0) taken by Xing Gao in Xingming Observatory Sky Survey(C42) around Dec. 16.64736 UT using a unfiltered CCD ( +Celestron C14 SchmidtCassegrain telescope D=356mm @f/6.9 ). The transient approximately located at R.A.=00h42m20.50s +41d14’59”.9(equinox 2000.0).Which is about 268.6″ west and 68.6″ south of the center of the NGC224(M31). Nothing is visible at this position on archival images taken on Dec. 13.52853 UT(limiting mag 19.0).
