POSSIBLE NOVA IN M31 – PSP22P

Jingyuan Zhao, Mi Zhang, Jiangao Ruan, Guoyou Sun, Jianlin Xu, Yi Ding and Xing Gao (Xingming Observatory), report the discovery of M31N 2017-01e possible recurrent outburst in 2022. 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 .

翻阅历史图时发现,疑似再发新星。曾在2017年1月底(M31N 2017-01e,日本业余天文学家板垣公一发现,利物浦望远镜光谱证认为He/N型经典新星,同时指出光谱特征与一些再发新星类似)、2019年9月底(M31N 2019-09d,PSP发现,变暗迅速,因此未被证认)爆发。若是再发新星且爆发是准周期的,那么下次爆发应在2024年9月前后
