Yingbin Nie, Wenjie Zhou, Mi Zhang, Jiangao Ruan, Jingyuan Zhao, Jianlin Xu, Yanxi Li, Yi Ding, Guoyou Sun, Xing Gao (Xingming Observatory), report the discovery of an UV candidate (17.25+-0.03G). The source appears to correspond to object Gaia EDR3 387456593274427904 (19.37 G) in the Gaia EDR3. Discovery was made on one 30-s survey image (limiting mag about 19.0) taken by Xing Gao around 2021 Nov 14.59189 UT at Xingming Observatory #2 (N89) using a unfiltered CCD (0.5-m f/4 reflector). Images can be found at: http://xjltp.china-vo.org/psp21ai.html Follow-up observations were performed by Xing Gao at Xingming Observatory #3 (N88) around Nov. 14.65875, 2021 UT using a unfiltered CCD (+ 0.6-m f/8 Ritchey-Chretien telescope). Several 90-s survey images (limiting mag about 21.0) showed that the candidate has decreased to 19.32+-0.08G, 14.65875 UT; 19.35+-0.09G, 14.66002 UT. The candidate likely to be an UV star.
