Mi Zhang, Xing Gao (Xingming Observatory) report/s the discovery of a new astronomical transient.
IAU Designation: AT 2021jwr
Discoverer internal name: XM53MZ
Coordinates (J2000): RA = 00:42:46.560 (10.694) DEC = +41:14:26.30 (41.240639)
Discovery date: 2021-04-16 22:03:26.000 (JD=2459321.4190509)
Potential host galaxy: M31
Remarks: Mi Zhang, Xing Gao (Xingming Observatory), report the discovery of a possible nova (mag approximately 18.0) on several 300-s survey images (limiting mag about 19.0) taken by Xing Gao at Xingming Observatory #3 (N88) around Apr. 16.91905, 2021 UTC using a unfiltered CCD (+ 0.6-m f/8 Ritchey-Chretien telescope). The transient approximately located at R.A.=00h42m46.56s +41d14’26”.3 (equinox 2000.0). Which is about 25.3" east and 102.2" south of the center of the NGC224 (M31). Nothing is visible at this position on archival images taken on Apr. 15.89840, 2021 (limiting mag 18.5). Images can be found at: http://xjltp.china-vo.org/xm53mz.html
