THE DISCOVERY OF A CV CANDIDATE – XM94HT

Hanjie Tan (AUUK), Guoyou Sun, Mi Zhang, Jiangao Ruan, Jingyuan Zhao (Xingming Obs), Quanzhi Ye , Xing Gao (Xingming Obs), report the discovery of a possible CV at 17.48 Gmag on several 60-s survey images (limit mag about 18.5) taken by Xing Gao at Xingming Observatory “#”3 (N88) around 2022 Jan.10.63007 UTC using unfiltered CCD and PAT telescope (0.3-m f/3.6 reflector). The transient is approximately located at RA= 02h08m15.98s,DEC = +58d10m16.5s (equinox 2000.0). Discovery images can be found at: http://xjltp.china-vo.org/xm94ht.html

Follow-up observations were performed by Xing Gao at Xingming Observatory #3 (N88) around 2022 Jan.11.73338 UT using a unfiltered CCD (+ 0.6-m f/8 Ritchey-Chretien telescope). Several 300-s survey images (limiting mag about 19.0) showed that the candidate was 1.9” close to Gaia DR2 506739448679215232. The candidate likely to be a CV.
