Mi Zhang and Xing Gao report/s the discovery of a new astronomical transient.
IAU Designation: AT 2021pap
Discoverer internal name: XM54MZ
Coordinates (J2000): RA = 00:43:05.870 (10.774458) DEC = +41:15:48.00 (41.263333)
Discovery date: 2021-06-06 20:04:57.000 (JD=2459372.3367708)
Potential host galaxy: M31
Remarks: Mi Zhang and Xing Gao, report the discovery of a possible nova (mag approximately 17.4) on several 300-s survey image (limiting mag about 19.5) taken by Xing Gao at Xingming Observatory #2 (N89) around June. 06.83677 UTC using a unfiltered CCD (+ 0.6-m f/8 Ritchey-Chretien telescope). The transient approximately located at R.A.=00h43m05.87s +41d15’48”.0 (equinox 2000.0). Which is about 243.0" east and 20.5" south of the center of the NGC224(M31). Nothing is visible at this position on archival images taken on May. 28.89162 (limiting mag 18.5) . Images can be found at: http://xjltp.china-vo.org/xm54mz.html
